摘要： A quantum source coding method includes: initializing a quantum register having a plurality of nodes; loading a unary-coded message into the quantum register; loading an address state into an address register of each message node of the quantum register; sorting the message nodes based on a data register such that the message nodes form a message-sorted sequence; and applying, for each message node at an end of the message-sorted sequence, a CNOT gate to the address state of each of the register's message nodes and output nodes. The method also includes: unsorting the message nodes; sorting the nodes based on the address register such that the nodes form a fully-sorted sequence; applying, for each pair of adjacent nodes in the fully-sorted sequence having the same address state, a CNOT gate to the data registers of each pair; and unsorting the nodes to return the fully-sorted sequence to the initial sequence.

摘要： A system and method for a quantum-enhanced optimizer (QEO) using quantum generative models to achieve lower minimum cost functions than classical or other known optimizers. In a first embodiment, the QEO operates as a booster to enhance the performance of known stand-alone optimizers in complex instances where known optimizers have limitations. In a second embodiment, the QEO operates as a stand-alone optimizer for finding a minimum with the least number of cost-function evaluations. The disclosed QEO methods outperform known optimizers, including Bayesian optimizers. The disclosed quantum-enhanced optimization methods may be based on tensor networks. The generative models may also be based on classical, quantum, or hybrid quantum-classical approaches, including Quantum Circuit Associative Adversarial Networks (QC-AAN) and Quantum Circuit Born Machines (QCBM).

摘要： The present disclosure describes various methods, systems, and storage medium for engineering fast bias-preserving gates on stabilized cat qubits. One method for performing a quantum operation on a qubit using a noise-bias-preserving (NBP) quantum gate includes obtaining and stabilizing the qubit: determining a type of the NBP quantum gate associated with the quantum operation, according to type of the NBP quantum gate, the quantum operation on the qubit to obtain a modified qubit, the quantum operation comprising a base gate drive and a counterdiabatic (CD) control drive. Another method for stabilizing a qubit for quantum storage includes obtaining a qubit; in response to the qubit being in an idle state, applying a two-photon dissipation operation on the qubit to stabilize the qubit, the two-photon dissipation operation corresponding to a two-photon drive.

摘要： Techniques facilitating quick waveform revisions following quantum system calibrations. In one example, a system can comprise a processor that executes computer executable components stored in memory. The computer executable components comprise: a calibration component; and a regeneration component.
