‘Breakthrough’ echoed across science journal headlines these past few weeks in the world of quantum computing. Scientists across the globe are focused on advancing the capabilities of quantum computing and barriers are falling.
Some of the breakthrough headlines include:
A new type of magnetism was discovered by MIT researchers by supercooling a crystal. The crystal displays a quantum spin ‘liquid state’ a phenomenon that may allow distant particles to affect each other’s magnetism and which could be useful in the design of quantum computers.
A team of Australian engineers were able to show that the nucleus of an atom could be controlled by electric fields rather than magnetic fields. The behavior was predicted as early as 1961 but only now has an experiment been able to achieve it. Being able to control individual atoms at the nanometer level can help build quantum computers and quantum sensors.
An Australian scientist at the University of Sydney developed a technique to improve error correction in quantum calculations. The new technique should make quantum computers significantly more efficient in their computations.
Researchers at the University of Chicago discovered a way to control and integrate quantum states with everyday electronics. The team was able to control quantum states in silicon carbide rather than using ‘exotic materials’. Silicon carbide is easy to work with. Their work also found that the use of electric fields rather than lasers can results in more stable quantum states.
