摘要： According to an aspect of an embodiment, operations include receiving a dataset associated with a machine learning task, preparing an input quantum state based on the dataset, and preparing a VQC to function as a QNN. The operations further include executing operations comprising reading content of a state buffer as empty or including past information on parameters of the QNN, selecting parameter values based on the content, preparing an input for an optimizer network based on the parameter values, computing an output by applying the optimizer network on the input, updating the parameter values using the output, and obtaining a current cost function value based on the updated parameter values. The operations further include updating the state buffer using the current cost function value and the updated parameters values and training the QNN until the current cost function value is below a threshold.

摘要： A computer-implemented method and system for implementing a n-fold fermionic excitation generator using linear combination of directly differentiable operators on a quantum computer. Computer-readable data is generated and stored which when executed on the quantum computer, causes a quantum circuit of the quantum computer to execute repeatedly to perform a sequence of operations that implements the unitary (I) generated by a fermionic n-fold excitation operator G. The Gradient with respect to the angle Θ of arbitrary expectation values involving the unitary operation can, in the general case, be evaluated by four expectation values obtained from replacing the corresponding unitary with fermionic shift operations (II). Fermionic shift operations can be constructed through the original unitary and unitary operations generated by the nullspace projector P0 of the fermionic excitation generator. Other operators and generators are disclosed.

摘要： Arrangements for intelligent orchestration of quantum programs using smart contracts linked to quantum program non-fungible tokens (NFTs) are provided. A plurality of quantum programs to be executed on target quantum hardware may be received from a digital computing device. NFTs representing each of the plurality of quantum programs may be created and linked to a corresponding quantum program. The NFTs may be stored on a distributed ledger and controlled by smart contracts storing predefined acceptance rules based on which a quantum processing output is deployed to the digital computing device. A quantum program may be validated for respective target quantum hardware by validating the NFT associated with the quantum program. The respective target quantum hardware may ingest the validated quantum program and perform quantum processing. Responsive the output of quantum processing meeting the predefined acceptance criterion, the output of the quantum processing may be deployed in the digital computing device.

摘要： Methods, systems and apparatus for implementing iSWAP quantum logic gates between a first qubit and a second qubit. In one aspect, a method includes implementing a cascade schedule that defines a trajectory of a detuning between a frequency of the first qubit and a frequency of the second qubit. Implementing the cascade schedule includes: during a first stage, adiabatically driving detuning between the frequency of the first qubit and the frequency of the second qubit through a first avoided crossing in a leakage channel; during a second stage, driving detuning between the frequency of the first qubit and the frequency of the second qubit through a second avoided crossing in a swap channel; during a third stage, evolving the first qubit and second qubit; during a fourth stage, implementing the second stage in reverse order; and during a fifth stage, implementing the first stage in reverse order.

摘要： A process for bang-anneal-bang quantum optimization includes: identifying base curve v(t); setting a total runtime of the process; creating an initial guess for parameters in an ansatz; creating an initial guess for parameters in an ansatz; evolving a quantum state from a ground state of B following Hamiltonian H(t)=u(t) B+(1−u(t)) C and, at termination of evolving the quantum state, measuring the resulting quantum state; updating the parameters for the ansatz based on the resulting quantum state; repetitively creating the ansatz for u(t), evolving the quantum state from the ground state of B following Hamiltonian H(t), and, at termination of evolving the quantum state, determining the resulting quantum state until the classical outer loop converges to a selected convergence limit; and returning the final form of u(t) to perform bang-anneal-bang quantum optimization.

摘要： Techniques for performing temporally encoded lattice surgery (TELS) protocols to reduce space-time costs of lattice surgery measurements are disclosed. A given quantum algorithm may be represented using Pauli-based computation, and associated multi-qubit Pauli operators may be encoded into codewords of a given classical error-correcting code. A hybrid error detection and correction scheme may then be applied during a given TELS protocol in which classical error syndromes corresponding to errors with weights up to a certain weight limit may be corrected while other classical error syndromes corresponding to errors with higher weights may cause given lattice surgery measurements to be remeasured. The weight limit for the hybrid scheme may be chosen based, at least in part, on a number of codewords used, a size of a parallelizable Pauli set used to represent the quantum algorithm, and a distance parameter of the chosen classical error-correcting code.
