Quantum physics is on the brink of many technological breakthroughs. However, the main obstacle is finding the right way to couple and precisely control a sufficient number of quantum systems (e.g. individual atoms). A team of researchers from TU Wien and Harvard University has found a new way to manipulate the quantum universe via tiny mechanical vibrations.

“Normally, diamonds are made exclusively of carbon, but adding silicon atoms in certain places creates defects in the crystal lattice where quantum information can be stored”, says Professor Peter Rabl from TU Wien. These microscopic flaws in the crystal lattice can be used like a tiny switch that can be switched between a state of higher energy and a state of lower energy using microwaves.

Together with a team from Harvard University, Peter Rabl’s research group has developed a new idea to achieve the targeted coupling of quantum memories within the diamond. One by one they can be built into a tiny diamond rod measuring only a few micrometres in length. Then this rod can then be made to vibrate, however, these vibrations are so small that they can only be described using quantum theory. It is through these vibrations that the silicon atoms can form a quantum-mechanical link to each other. (1)

We are unique.

Simply by raising our voice.

Inside a silent cosmos.

And within that silence…

We become one with the universe.

Walking quietly inside the forest.

Being alone and yet full.

Inside a silent cosmos…

The leaves of the trees rustle…

Memories stored inside a diamond.

Eternal. Meaningless.

Stepping on the diamond.

Inside the dirt.

Open your mouth.

Trying to speak…

No sound coming out of your mouth…

The diamond shining more than ever within Earth’s bosom…

Stay still. Move. Logos. Silence.

Quantum mechanics is truly weird. Objects can behave like both particles and waves, and can be both here and there at the same time, defying our common sense. Such counterintuitive behaviour is typically confined to the microscopic realm and the question “why don’t we see such behaviour in everyday objects?” challenges many scientists today.

A team of researchers developed a new technique to generate this type of quantum behaviour in the motion of a tiny drum just visible to the naked eye. The details of their research were published in New Journal of Physics. In the quantum world, a drum can vibrate and stand still at the same time. However, generating such quantum motion is very challenging. Lead author of the project Dr Martin Ringbauer, said: “You need a special kind of drumstick to make such a quantum vibration with our tiny drum”. To that end, scientists used laser light as a type of drumstick. (1)

Moving and yet standing still. Vibrating and non-vibrating at the same time. Talking while staying silent. The meaning of the cosmos is revealed in the irrational.

Yes, in the beginning there was Logos.

But who said it consisted of logic?

The meaning of life is manifested in the meaningless.

As I listen to you, I start to remember now.

That I know that voice. I’ve heard it before.

In the songs of the birds.

In the rustling of leaves in the morning breeze.

But most of all, I hear my voice in the forest.

In the deafening morning silence…

Causality debunked.

Researchers at the University of Vienna and the Austrian Academy of Sciences develop a new theoretical framework to describe how causal structures in quantum mechanics transform. They analyze under which conditions quantum mechanics allows the causal structure of the world to become “fuzzy.” In this case, a fixed order of events is not possible. The results were published in the journal Physical Review X.

The idea that events occur one after the other in a fixed causal order is part of our intuitive picture of the physical world. Imagine that Alice can send a message to Bob via a wire that connects them. Alice decides to have a barbecue and can invite Bob via the wire connection. If he gets invited, Bob decides to prepare some Ćevapčići to bring along. This is an example where the event in which Alice decides to invite Bob to the barbecue influences the event in which Bob decides to prepare food. Such an order of events characterizes a definite causal structure. However, research in the foundations of quantum mechanics suggests that, at the quantum level, causal structures may be “indefinite”. In an indefinite causal structure there might not be a fixed order in which events happen, i.e. whether Alice influences Bob or Bob influences Alice might not be defined.

“Our results demonstrate that under physically reasonable assumptions of continuity and reversibility a world with definite causal order will never become a world with an indefinite causal order and vice versa”, says Esteban Castro, one of the authors of the paper. This insight may lead to a more complete understanding of what the role of causality is in the quantum world. (1)

In the beginning there was chaos.

And then the cosmos was born.

We like to look into patterns.

We like to indulge into our hallucinations.

But every night, when we fall asleep, we remember.

It is not the Sun we celebrate.

What exists cannot change.

We are not scientists.

We are poets.

Admiring the Moon…

From electrons to photons. From photons to electrons…

The quantum computer of the future will be able to carry out computations far beyond the capacity of today’s computers. Quantum superpositions and entanglement of quantum bits (qubits) make it possible to perform parallel computations.

Making useful computations requires large numbers of qubits and it is this upscaling to large numbers that is providing a challenge worldwide. “To use a lot of qubits at the same time, they need to be connected to each other; there needs to be good communication”, explains researcher Nodar Samkharadze. At present the electrons that are captured as qubits in silicon can only make direct contact with their immediate neighbors. That makes it tricky to scale up to large numbers of qubits.

Some quantum systems use photons for long-distance interactions. Delft scientists have shown that a single electron spin and a single photon can be coupled on a silicon chip. This coupling makes it possible in principle to transfer quantum information between a spin and a photon. This is important to connect distant quantum bits on a silicon chip, thereby paving the way to upscaling quantum bits on silicon chips. (1)

Once the cosmos just was. In the beginning there was darkness.

And then came light. Making things visible. Splitting the cosmos into multiple pieces. A cosmos seemingly full of antinomies. And yet still solid and consistent as that first dark night…

Now we transfer the cosmos back into the light. A light which will interfere with itself. Only to show that the zillions of possibilities exist at the same time.

Some time ago, the cosmos was born into light.

But the light will fade away.

One electron at a time…

The pieces are going to disappear.

One interaction at a time…

The universe is going to die.

And only then, will we see that it was never born…

Quantum entanglement in living organisms? The complexity of simple definitions.

Researchers managed to generate and study quantum entanglement in living organisms.

In the study, scientists used green fluorescent proteins, which are responsible for bioluminescence and commonly used in biomedical research. The research team attempted to entangle the photons generated from the fluorescing molecules within the algae’s barrel-shaped protein structure by exposing them to spontaneous four-wave mixing, a process in which multiple wavelengths interact with one another to produce new wavelengths.

Through a series of these experiments, researchers successfully demonstrated a type of entanglement, called polarization entanglement, between photon pairs. (polarization is the orientation of oscillations in light waves. A wave can oscillate vertically, horizontally, or at different angles) In the entangled pairs, the photons’ polarizations are entangled, meaning that the oscillation directions of light waves are linked. Scientists also noticed that the barrel-shaped structure surrounding the fluorescing molecules protected the entanglement from being disrupted.

“When I measured the vertical polarization of one particle, we knew it would be the same in the other”, a researcher said. “If we measured the horizontal polarization of one particle, we could predict the horizontal polarization in the other particle. We created an entangled state that correlated in all possibilities simultaneously”. (1)

Sounds fascinating. But what did we do here? We created entanglement not for something living but for atoms (photons) related to a specific organism. So? Why is that important? Are the atoms related to a living organism less “atomic” than the other atoms related to non-living organisms?

Our definitions are so simplistic. The razor of Occam has cut down everything to a point that there is no way to add the necessary complexity to study the real world without destroying the whole foundations of science altogether. We tend to find the simplest solution (everything is matter) and yet the reality is much more complex (the cosmos is matter and immaterial spirit, with the later actually creating and giving essence to the former).

The foundations of science are illusionary.

And that is why it reaches to illusionary (extraordinary) results.

Look at religion. Its foundations are the humans themselves.

And that is why it will never see entanglement.

Not because it cannot. But because entanglement is not there.

And what is most important: It does not matter.

Stop building upon shadows.

Touch yourself. Start clapping.

And the world will make sense again.
