The readout fidelity reached an impressive 98 percent for 4-photon events and 90 percent for 6-photon events. Furthermore, the researchers proposed a dual-channel timing setup to enable real-time ...
In a new take on quantum logic spec­troscopy, a sensi­tive spec­troscopy method employing a Schrödinger cat state of motion is inves­ti­gated. With sensi­tivity down to the single photon level, the ...
