摘要： A method of performing simultaneous entangling gate operations in a trapped-ion quantum computer includes selecting a gate duration value and a detuning frequency of pulses to be individually applied to a plurality of participating ions in a chain of trapped ions to simultaneously entangle a plurality of pairs of ions among the plurality of participating ions by one or more predetermined values of entanglement interaction, determining amplitudes of the pulses, based on the selected gate duration value, the selected detuning frequency, and the frequencies of the motional modes of the chain of trapped ions, generating the pulses having the determined amplitudes, and applying the generated pulses to the plurality of participating ions for the selected gate duration value. Each of the trapped ions in the chain has two frequency-separated states defining a qubit, and motional modes of the chain of trapped ions each have a distinct frequency.

摘要： The present disclosure provides methods and systems for performing non-classical computations. The methods and systems generally use a plurality of spatially distinct optical trapping sites to trap a plurality of atoms, one or more electromagnetic delivery units to apply electromagnetic energy to one or more atoms of the plurality to induce the atoms to adopt one or more superposition states of a first atomic state and a second atomic state, one or more entanglement units to quantum mechanically entangle at least a subset of the one or more atoms in the one or more superposition states with at least another atom of the plurality, and one or more readout optical units to perform measurements of the superposition states to obtain the non-classical computation.

摘要： Collaborative filtering systems based on variational autoencoders (VAEs) are provided. VAEs may be trained on row-wise data without necessarily training a paired VAE on column-wise data (or vice-versa), and may optionally be trained via minibatches. The row-wise VAE models the output of the corresponding column-based VAE as a set of parameters and uses these parameters in decoding. In some implementations, a paired VAE is provided which receives column-wise data and models row-wise parameters; each of the paired VAEs may bind their learned column- or row-wise parameters to the output of the corresponding VAE. The paired VAEs may optionally be trained via minibatches. Unobserved data may be explicitly modelled. Methods for performing inference with such VAE-based collaborative filtering systems are also disclosed, as are example applications to search and anomaly detection.

摘要： A method for compiling a quantum circuit on a trapped-ion quantum processor includes: obtaining a quantum circuit containing a first predetermined category of two-qubit quantum gates, and/or one-qubit quantum gates; a separation of the quantum circuit into local layers, and entangling layers; compiling the local layers; compiling the entangling layers, separate from the step of compiling the local layers, transforming the quantum gates of those entangling layers so that they contain only collective or entangling N-qubit quantum gates of a third predetermined category, one-qubit quantum gates of a fourth predetermined category; and a step of grouping together the compiled local layers and the compiled entangling layers into a compiled quantum circuit.

摘要： A quantum entanglement communication service can be provided by detecting a request to access data stored at a first computer. In response to detecting the data access request, a request can be generated to request that a server computer generate an entangled particle pair. Measurement data can be received, the measurement data corresponding to a measurement observed after interacting a first bit of a token stored at a second computer with a first entangled particle from the entangled particle pair. An operation to perform on a second entangled particle of the entangled particle pair at the first computer can be determined and performed. A state of the second entangled particle can be measured to obtain a value, and a bit string can be generated, where the bit string can include a number that corresponds to the value.

摘要： Systems, computer-implemented methods, and/or computer program products that can facilitate target qubit decoupling in an echoed cross-resonance gate are provided. According to an embodiment, a computer-implemented method can comprise receiving, by a system operatively coupled to a processor, both a cross-resonance pulse and a decoupling pulse at a target qubit. The cross-resonance pulse propagates to the target qubit via a control qubit. The computer-implemented method can further comprise receiving, by the system, a state inversion pulse at the control qubit. The computer-implemented method can further comprise receiving, by the system, both a phase-inverted cross-resonance pulse and a phase-inverted decoupling pulse at the target qubit. The phase-inverted cross-resonance pulse propagates to the target qubit via the control qubit.
