Universal quantum control of an atomic qubit on a surface
Our paper demonstrates universal quantum control of an atomic spin qubit on surface using vector microwave control technique. We were able to control and measure an arbitrary superposition state of the spin, a significant step towards quantum applications of spin architectures at the atomic scale.
Mechanism for Fluctuating Pair Density Waves
Pair density waves (PDWs) and `fluctuating' PDWs (FPDWs) are modulated superconducting states that manifest in novel quantum materials. We provide a unified theoretical framework that explains the FPDW, PDW and ordinary (uniform) superconducting phases under a single paradigm.
Scientists discover light conversion in free space: a manifestation of the quantum van Cittert-Zernike theorem
A new article published in Nature’s npj Quantum Information demonstrates the possibility of producing different kinds of light through propagation in free space.
