Recently, a group of scientists used a two-qubit quantum system to model the energies of a hydrogen molecule and found that using an iterative algorithm to calculate each digit of the phase shift ...

After all, qubits are simple enough to be one logical bit ... To illustrate the theory, Fullwood and Vedral used a ‘toy model’ of a one-qubit universe. A toy model is an extremely simplified ...

This makes it the first company to clear the 100-qubit mark ... Quantum System 1 model and develop the ability to spread computation between cryostats. And that is not simple.

IBM's 2017-model, 16-qubit quantum processor ... At this stage, they have managed to demonstrate the technology using a simple two-qubit processor, and the results are impressive.

(Courtesy: IBM) A 127-qubit quantum processor has been used by an international ... quantum spins that interact with their nearest neighbours. Despite being very simple, the model is extremely ...

Quantum computers have their own version of the bit: the qubit. It, too ... can hardly be solved exactly even for relatively simple chains of just a few spins. Not exactly the best conditions ...

Built at the RIKEN RQC-FUJITSU Collaboration Center in Wako, Japan, the new system represents a fourfold increase in computational capacity compared to their previous 64-qubit model launched in 2023.

In this case, the qubit’s behavior lines up with the way we describe spacetime using regular Euclidean geometry. To illustrate the theory, Fullwood and Vedral used a ‘toy model’ of a one ...
