Quantinuum, Microsoft claim to have quieted quantum computing ‘noise’

Two of the leaders in quantum technologies, Quantinuum and Microsoft, today announced a breakthrough in reducing ‘noise’ that could mean quantum advantage is closer than previously thought. When it comes to quantum computing, noise refers to internal and external interference that lead to errors in quantum computations. Without properly conquering challenges such as variations in temperature, external electromagnetic fields, and quantum decoherence, quantum computers will not surpass the capabilities of classical computers.  Because of how prone they are to errors resulting from these kinds of interference, today’s machines are referred to as what is known as NISQ-era devices — Noisy…
