摘要： Systems and methods are provided for reading an associated state of a qubit. A first soliton is injected along a first Josephson transmission line coupled to the qubit. A velocity of the first soliton is selected according to a physical length of the qubit and a characteristic frequency of the qubit. A second soliton is injected at the selected velocity along a second Josephson transmission line that is not coupled to the qubit. A delay associated with the first soliton is determined relative to the second soliton.

摘要： An optical-microwave-quantum transducer can include a tapered optical fiber configured to transmit and receive optical signals. The optical-microwave-quantum transducer can also include a cantilever that can include an optical cavity that includes a nanophotonic crystal. The optical cavity can be configured to provide mechanical excitation in response to electromagnetic excitation induced by photons emitted from the tapered optical fiber. The cantilever can also include a mechanical coupler that is configured to induce electrical modulation onto a superconducting cavity in response to the mechanical excitation. The mechanical coupler can also be configured to provide mechanical excitation in response to electromagnetic excitation induced by photons from the superconducting cavity. The optical cavity can further be configured to provide electromagnetic excitation that induces optical modulation on the tapered optical fiber in response to the mechanical excitation.

摘要： An optical-microwave-quantum transducer can include a first nanophotonic slab and a second nanophotonic slab. Each of the first and second nanophotonic slabs can include an optical region and a superconducting region. The first nanophotonic slab can include a pair of torsional beams anchored to a substrate to allow relative rotation between the first and second nanophotonic slabs about an axis of rotation. The optical-microwave-quantum transducer can include a gap between the optical region of the first and second nanophotonic slabs that forms an optical cavity in response to an optical signal, wherein the optical cavity can induce mechanical oscillation of the first nanophotonic slab about the axis of rotation. The mechanical oscillation can induce electrical modulation on a superconducting cavity coupled to the superconducting regions of the first and second nanophotonic slabs.
