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.

Extra dimensions. Existence. Cosmos.

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)

Mind, waves, neural connections...

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.

Tarantulas… Colours… Evolution… Destiny…

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…
