- Abstract: Microwave quantum memory promises advanced capabilities for noisy
intermediate-scale superconducting quantum computers. Existing approaches to
microwave quantum memory lack complete combination of high efficiency, long
storage time, noiselessness and multi-qubit capacity. Here we report an
efficient microwave broadband multimode quantum memory. The memory stores two
spectral modes of single photon level microwave radiation in on-chip system of
eight coplanar superconducting resonators. Single mode storage shows a power
efficiency of up to $60\pm 3\%$ at single photon energy and more than $73\pm
3\%$ at higher intensity. The demonstrated efficiency is an order of magnitude
larger than the previously reported multimode microwave quantum memory. The
noiseless character of the storage is confirmed by coherent state quantum
process tomography. The demonstrated results pave the way to further increase
in efficiency and hence building a practical multimode microwave memory for
superconducting quantum circuits.
