A continuous optoacoustic system in a Brillouin waveguide enables high-fidelity storage and on-demand retrieval of squeezed and entangled optical states with bandwidths reaching hundreds of MHz.
Experimental demonstration of logical |H_L> and |T_L> magic states with fidelities 0.8806 and 0.8665 on IBM superconducting hardware using a qubit-efficient surface code embedding, with reported error thresholds above prior values.
Derives optimal time-dependent cavity linewidth modulations to maximize absorption and emission efficiency in spin ensemble memories, establishing an upper bound in the narrow bandwidth regime and a critical bandwidth threshold.
