I always wait to the end of time to wake up and drive to my office this daily routine is boring and doing the same tasks every day makes me act like a robot that’s why I've always been fascinated by quantum physics and the possibility of alternate realities* my work is demanding doing endless experiments and looking for the “black holes” is sometimes frustrating had I known that we were not going to get rid of this damned quantum jumping I never would have involved myself in this business and today today is one of those gray days and the only nice event is to meet Ana who returns from her vacations we agree to meet in a cozy little café near my office she is always interested in what I am working  on in my research and monothematic talks well the girl I find who wants to talk about quantum theory in a bar is the one I want to marry sweet Ana I am missing her a lot thinking of a little gift to surprise her I bought her a small crystal angel one more to her glass figures collection half way to my job I realize that I forgot to take it from the table damn I decide to go back and to take it I am already late  driving home I see a crowd near my house the police car many people on the intersection leading to my place no chance to move faster no possibility to turn back I am  stuck OK I leave my car on the street in all this chaos and I am walking down the narrow street returning home first cup of coffee I drink at work my boss is off today I can postpone the presentation of the project and think to collect more data to support the conclusion if it is correct it signifies the end of physics as a science I think I can safely say that nobody understands quantum mechanics I know that my project’s output makes absolutely no sense on my way home I stumble and fall on the sharp debris pain is terrible and I feel how a trickle of blood runs down my hand this is too much finally I am at the house’s door when oh where are the keys the crowd is around the car too close I feel being suffocated dizzy and isolated inside a transparent bubble people are knocking at the window it is rare I do not hear their voices they seem like being in an aquarium or it is I there do they want to help me Mike is not my best friend but I like his  sense of humor and wide smile he enters my office to ask about the report by the way there is an accident near your house they say on the radio I was driving fast as usual I was late I need go back to the car the keys must be there walking fast I was thinking that  there is no option other than to go straight to my work the meeting is held always in the morning and today I have to present the report from my research bad luck but Ana understands my distraction she even likes it sometimes and now she is laughing loudly again I like her smile and dark suntan I have a small surprise for you dear but I I started to look for excusing myself for being so absent minded oh I know you told me when I called you to the office suddenly she looks at me puzzled but what is this red spot on your hand are you wounded I look down on my  palm and see it is cut I do not feel any pain how come what a paradox if my wound is a reality I feel it ought to be very  painful I reach for a napkin and clean my hands I put the dirty napkin in my pocket I touch the pieces of the crashed glass I am sorry Ana the angel is broken I destroyed my collection it’s childish I do not like it and I am sorry I ever had anything to do with it I cannot believe Ana was so fond of her collection I am confused but if you are not completely confused you do not understand the reality from the crashed car the paramedics pull out a dead body and put it on the stretcher the ambulance siren starts yelling the trajectory of your life is no longer just one straight path to an eventuality but is instead one path of many on an ever-branching tree of possibilities

About the Author: 
I am MBA in finance. In my HS, I learned about the Schrödinger's cat, but I did not know if it was still alive. Wanting to check, I took a QM course and now I know that the cat is there, in the black box. Alive? In its 7th life?

Quantum Theories

F is for ... Free Will

Ideas at the heart of quantum theory, to do with randomness and the character of the molecules that make up the physical matter of our brains, lead some researchers to suggest humans can’t have free will.

A is for ... Alice and Bob

In quantum experiments, these are the names traditionally given to the people transmitting and receiving information. In quantum cryptography, an eavesdropper called Eve tries to intercept the information.

Z is for ... Zero-point energy

Even at absolute zero, the lowest temperature possible, nothing has zero energy. In these conditions, particles and fields are in their lowest energy state, with an energy proportional to Planck’s constant.

I is for ... Interferometer

Some of the strangest characteristics of quantum theory can be demonstrated by firing a photon into an interferometer: the device’s output is a pattern that can only be explained by the photon passing simultaneously through two widely-separated slits.

G is for ... Gluon

These elementary particles hold together the quarks that lie at the heart of matter.

B is for ... Bell's Theorem

In 1964, John Bell came up with a way of testing whether quantum theory was a true reflection of reality. In 1982, the results came in – and the world has never been the same since!

Y is for ... Young's Double Slit Experiment

In 1801, Thomas Young proved light was a wave, and overthrew Newton’s idea that light was a “corpuscle”.

R is for ... Reality

Since the predictions of quantum theory have been right in every experiment ever done, many researchers think it is the best guide we have to the nature of reality. Unfortunately, that still leaves room for plenty of ideas about what reality really is!

S is for ... Schrödinger’s Cat

A hypothetical experiment in which a cat kept in a closed box can be alive and dead at the same time – as long as nobody lifts the lid to take a look.

D is for ... Dice

Albert Einstein decided quantum theory couldn’t be right because its reliance on probability means everything is a result of chance. “God doesn’t play dice with the world,” he said.

I is for ... Information

Many researchers working in quantum theory believe that information is the most fundamental building block of reality.

S is for ... Superposition

Quantum objects can exist in two or more states at once: an electron in superposition, for example, can simultaneously move clockwise and anticlockwise around a ring-shaped conductor.

W is for ... Wave-particle duality

It is possible to describe an atom, an electron, or a photon as either a wave or a particle. In reality, they are both: a wave and a particle.

J is for ... Josephson Junction

This is a narrow constriction in a ring of superconductor. Current can only move around the ring because of quantum laws; the apparatus provides a neat way to investigate the properties of quantum mechanics.

O is for ... Objective reality

Niels Bohr, one of the founding fathers of quantum physics, said there is no such thing as objective reality. All we can talk about, he said, is the results of measurements we make.

X is for ... X-ray

In 1923 Arthur Compton shone X-rays onto a block of graphite and found that they bounced off with their energy reduced exactly as would be expected if they were composed of particles colliding with electrons in the graphite. This was the first indication of radiation’s particle-like nature.

G is for ... Gravity

Our best theory of gravity no longer belongs to Isaac Newton. It’s Einstein’s General Theory of Relativity. There’s just one problem: it is incompatible with quantum theory. The effort to tie the two together provides the greatest challenge to physics in the 21st century.

C is for ... Computing

The rules of the quantum world mean that we can process information much faster than is possible using the computers we use now.

P is for ... Planck's Constant

This is one of the universal constants of nature, and relates the energy of a single quantum of radiation to its frequency. It is central to quantum theory and appears in many important formulae, including the Schrödinger Equation.

A is for ... Act of observation

Some people believe this changes everything in the quantum world, even bringing things into existence.

H is for ... Hidden Variables

One school of thought says that the strangeness of quantum theory can be put down to a lack of information; if we could find the “hidden variables” the mysteries would all go away.

P is for ... Probability

Quantum mechanics is a probabilistic theory: it does not give definite answers, but only the probability that an experiment will come up with a particular answer. This was the source of Einstein’s objection that God “does not play dice” with the universe.

M is for ... Multiverse

Our most successful theories of cosmology suggest that our universe is one of many universes that bubble off from one another. It’s not clear whether it will ever be possible to detect these other universes.

B is for ... Bose-Einstein Condensate (BEC)

At extremely low temperatures, quantum rules mean that atoms can come together and behave as if they are one giant super-atom.

T is for ... Tunnelling

This happens when quantum objects “borrow” energy in order to bypass an obstacle such as a gap in an electrical circuit. It is possible thanks to the uncertainty principle, and enables quantum particles to do things other particles can’t.

K is for ... Kaon

These are particles that carry a quantum property called strangeness. Some fundamental particles have the property known as charm!

A is for ... Atom

This is the basic building block of matter that creates the world of chemical elements – although it is made up of more fundamental particles.

Q is for ... Qubit

One quantum bit of information is known as a qubit (pronounced Q-bit). The ability of quantum particles to exist in many different states at once means a single quantum object can represent multiple qubits at once, opening up the possibility of extremely fast information processing.

S is for ... Schrödinger Equation

This is the central equation of quantum theory, and describes how any quantum system will behave, and how its observable qualities are likely to manifest in an experiment.

C is for ... Cryptography

People have been hiding information in messages for millennia, but the quantum world provides a whole new way to do it.

R is for ... Randomness

Unpredictability lies at the heart of quantum mechanics. It bothered Einstein, but it also bothers the Dalai Lama.

U is for ... Uncertainty Principle

One of the most famous ideas in science, this declares that it is impossible to know all the physical attributes of a quantum particle or system simultaneously.

T is for ... Teleportation

Quantum tricks allow a particle to be transported from one location to another without passing through the intervening space – or that’s how it appears. The reality is that the process is more like faxing, where the information held by one particle is written onto a distant particle.

R is for ... Radioactivity

The atoms of a radioactive substance break apart, emitting particles. It is impossible to predict when the next particle will be emitted as it happens at random. All we can do is give the probability that any particular atom will have decayed by a given time.

L is for ... Light

We used to believe light was a wave, then we discovered it had the properties of a particle that we call a photon. Now we know it, like all elementary quantum objects, is both a wave and a particle!

H is for ... Hawking Radiation

In 1975, Stephen Hawking showed that the principles of quantum mechanics would mean that a black hole emits a slow stream of particles and would eventually evaporate.

N is for ... Nonlocality

When two quantum particles are entangled, it can also be said they are “nonlocal”: their physical proximity does not affect the way their quantum states are linked.

Q is for ... Quantum biology

A new and growing field that explores whether many biological processes depend on uniquely quantum processes to work. Under particular scrutiny at the moment are photosynthesis, smell and the navigation of migratory birds.

U is for ... Universe

To many researchers, the universe behaves like a gigantic quantum computer that is busy processing all the information it contains.

D is for ... Decoherence

Unless it is carefully isolated, a quantum system will “leak” information into its surroundings. This can destroy delicate states such as superposition and entanglement.

W is for ... Wavefunction

The mathematics of quantum theory associates each quantum object with a wavefunction that appears in the Schrödinger equation and gives the probability of finding it in any given state.

L is for ... Large Hadron Collider (LHC)

At CERN in Geneva, Switzerland, this machine is smashing apart particles in order to discover their constituent parts and the quantum laws that govern their behaviour.

M is for ... Many Worlds Theory

Some researchers think the best way to explain the strange characteristics of the quantum world is to allow that each quantum event creates a new universe.

V is for ... Virtual particles

Quantum theory’s uncertainty principle says that since not even empty space can have zero energy, the universe is fizzing with particle-antiparticle pairs that pop in and out of existence. These “virtual” particles are the source of Hawking radiation.

E is for ... Entanglement

When two quantum objects interact, the information they contain becomes shared. This can result in a kind of link between them, where an action performed on one will affect the outcome of an action performed on the other. This “entanglement” applies even if the two particles are half a universe apart.
