Gate modulation of the hole singlet-triplet qubit frequency in germanium
Researchers have demonstrated a S − T_ qubit whose frequency is a strong function of the voltage applied to the barrier gate shared by the quantum dots.
New method to control electron spin paves the way for efficient quantum computers
Researchers have developed a new method for manipulating information in quantum systems by controlling the spin of electrons in silicon quantum dots. The results provide a promising new mechanism for control of qubits, which could pave the way for the development of a practical, silicon-based quantum computer.
Magnons Unveiled: A Quantum Leap in Materials Science
Research shows that spinning quasiparticles, or magnons, light up when paired with a light-emitting quasiparticle, or exciton, with potential quantum information applications.
