英国萨里大学研究人员提出了一种新型量子比特设计，利用超流氦-3的独特性质来降低量子计算中的错误率。1这种被称为SHOQ设备（超流氦振荡器量子设备）的新型比特采用不带电的液态超流氦-3作为介质，能够自然屏蔽某些类型的电磁噪声。1根据研究预测，该设备的错误率可能约为传统超导量子比特的1%，即低约100倍。1
该研究由萨里大学量子科学组领导，美国西北大学教授詹斯·科赫参与合作。1相关论文已发表在《npj Quantum Information》期刊。1研究员普里亚·沙玛博士表示："数学告诉我们它应该有效。下一步是制造原型并验证这些预测。"1虽然SHOQ设备需要在极低温度下运行，但研究团队指出，在此前的超流氦-3实验中已经成功达到了所需的运行条件。1
Scientists at the University of Surrey have introduced a novel quantum bit design based on superfluid helium that could dramatically reduce errors in quantum computing.1 The device, called SHOQ (Superfluid Helium Oscillator Quantum device), utilizes uncharged superfluid helium-3 to naturally shield against certain types of electromagnetic noise.1 According to the research, the error rate of this new design is expected to be approximately 1% that of conventional superconducting qubits—a reduction of about 100 times.1
The breakthrough addresses a critical challenge in scaling quantum computers, where error rates have limited practical applications.1 The SHOQ device leverages the unique properties of superfluid helium-3, a liquid form of helium that lacks electrical charge, to achieve superior noise resistance.1 The research, conducted by Surrey's Quantum Science group in collaboration with Professor Jens Koch from Northwestern University in the United States, has been published in npj Quantum Information with DOI: 10.1038/s41534-026-01355-3.1
Dr. Priya Sharma, a researcher on the project, stated that "the mathematics tells us it should work" and emphasized that the next phase involves building a prototype to verify these theoretical predictions.1 While the SHOQ device would need to operate at extremely low temperatures, previous experiments with superfluid helium-3 have already achieved the necessary conditions for such operation.1
