Superfluid helium qubit design could cut quantum computing errors
Quantum computers use qubits to process information in ways that are not possible with conventional computers. One of today’s leading approaches relies on superconducting circuits, but these are extremely sensitive to electromagnetic noise and stray electrical charges – similar…
The concept is the first reported design for a superfluid-based qubit, with the team’s calculations predicting error rates around 100 times lower than conventional superconducting qubits. Dr Priya Sharma, Daphne Jackson Fellow in Hybrid Quantum Systems at the University of Surrey’s School of Mathematics and Physics, and lead author of the study, said:
“We are not the first to think about the individual components behind this idea, but what we have done for the first time is bring them together in a microfluidic device and work out the specific details that could enable the device to function…
