Noise Fuels Quantum Leap, Boosting Qubit Performance by 700%
- westurner 3y ago> We suggest a completely different approach. Instead of getting rid of noise, we use continuous real-time noise surveillance and adapt the system as changes in the environment happen,” says Ph.D. Researcher at NBI Fabrizio Berritta, lead author on the study. [...] > The protocol behind the new findings integrates a singlet-triplet spin qubit implemented in a gallium arsenide double quantum dot with FPGA-powered qubit controllers. The qubit involves two electrons, with the states of both electrons entangled.
