Loss-induced quantum nonreciprocity
Here, we take a counterintuitive stance by engineering loss to generate a vital form of nonreciprocal quantum correlations, termed nonreciprocal photon blockade. we shown that a robust nonreciprocal single- and two-photon blockade can be achieve in a dissipative three-cavity system.
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.
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.
