Researchers demonstrate universal control of a quantum dot-based system with four singlet-triplet qubits
Being able to precisely manipulate interacting spins in quantum systems is of key importance for the development of reliable and highly performing quantum computers. This has proven to be particularly challenging for nanoscale systems with many spins that are based on quantum dots (i.e., tiny semiconductor devices).Quantum Physics NewsRead More
Lattice QCD method suggests a simpler spectrum of exotic XYZ hadrons
An elusive particle that first formed in the hot, dense maelstrom of the early universe has puzzled physicists for decades. Following its surprise discovery in 2003, scientists began observing a slew of other strange objects tied to the millionths of a second after the Big Bang.Quantum Physics NewsRead More
