A short time ago we were talking a handful of QuBits, now billions? Implications for 'unsolvable' problems?
Spin Control Method Brings Billion-Qubit Quantum Chips Closer
UNSW Sydney Newsroom (Australia) January 13, 2023
Engineers at Australia's University of New South Wales, Sydney (UNSW Sydney) and quantum computing spin-off Diraq have found a new approach for controlling single-electron spins in quantum dots with precision. The researchers can manipulate a single quantum bit (qubit)'s quantum state using electric fields rather than magnetic fields. The intrinsic spin-orbit electric dipole spin resonance effect "removes the requirement of placing extra structures around each [logic] gate," according to Diraq's Will Gilbert. UNSW's Andrew Dzurak said, "Since it's based on the same CMOS [complementary metal-oxide semiconductor] technology as today's computer industry, our approach will make it easier and faster to scale up for commercial production and achieve our goal of fabricating billions of qubits on a single chip."...
