A proposed qubit made with superfluid helium could cut quantum computing error rates by around 100 times by shielding quantum information from common forms of electromagnetic noise. If experiments confirm the predictions, the technology could eventually work alongside today’s superconducting qubits or serve as a new kind of quantum memory.

New parallel gate entangles diamond qubits 10 times faster at room temperature
Quantum technologies rely on qubits, units of information that can exist in combinations of the states 0 and 1 instead of being limited to one or the other like conventional bits. Qubits can become entangled, which means their states become linked in ways that cannot be explained
