Researchers have proposed an unusual new quantum bit built around superfluid helium-3 that calculations suggest could be around 100 times less error-prone than conventional superconducting qubits. The concept, developed by scientists at the University of Surrey in collaboration with Northwestern University, aims to tackle one of quantum computing’s biggest problems: protecting extremely fragile quantum information from environmental noise. Instead of storing information primarily in electrically charged superconducting circuits, the proposed device would exploit quantized mechanical oscillations in electrically neutral superfluid helium. Because the superfluid carries no electric charge, researchers predict that the system could be naturally less sensitive to some forms of electromagnetic and electrical noise that disturb today's quantum processors. The device remains theoretical and has not yet been experimentally demonstrated. The team's next major step is to build a prototype and test whether the predicted reduction in errors can be achieved in practice.
