Abstract: The disclosure describes various aspects of a software-defined quantum computer. For example, a method is described for generating an intermediate representation of source code for a software-defined quantum computer. The method includes performing a lexical analysis on a high-level intermediate representation of a quantum programming language; performing semantic analysis on an output of the lexical analysis; and generating a mid-level intermediate representation of the quantum programming language based on an output of the semantic analysis.

Abstract: The disclosure describes various aspects of acousto-optic modulator (AOM) configurations for quantum processing. A method is described including generating, by a first AOM from a laser beam, first and second diffracted laser beams at different angles based on first and second radio frequency (RF) tones. An optical component focuses the diffracted laser beams onto a second AOM, which generates third and fourth diffracted laser beams based on the first RF tone and a third RF tone and the second RF tone and a fourth RF tone respectively, wherein the third and fourth diffracted laser beams are substantially parallel when incident on a respective ion in a chain of ions in a trap. Quantum information in the ion is controlled to perform quantum processing based on the third and fourth diffracted laser beams. Another method is described including generating, by an AOM, a small polarization rotation of an undiffracted laser beam.

Abstract: The disclosure describes various aspects of a software-defined quantum computer. For example, a software-defined quantum computing architecture for allocating qubits is described that includes an application programming interface (API); a quantum operating system (OS) on which the API executes, with the quantum OS including a resource manager and a switch; and a plurality of quantum cores connected by the switch of the quantum resource OS. Moreover, the resource manager of the quantum resource OS determines an allocation of a plurality of qubits in the plurality of quantum cores.

Abstract: Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, for background-free qubit measurement. In some aspects, a method includes controlling a photon source oriented to direct photons towards ion(s) in an ion trap to produce photons having a first wavelength for a first time period; stopping the photon source from producing photons having the first wavelength; activating a photon detector configured to detect photons having the first wavelength; controlling the photon source to produce photons having a second wavelength different than the first wavelength for a second time period; detecting photons having the first wavelength during the second time period; and determining, based on detection of photons having the first wavelength during the second time period, that at least one of the one or more ions is in a |1> state.

Abstract: The disclosure describes aspects of laser cavity repetition rate tuning and high-bandwidth stabilization of pulsed lasers. In one aspect, an output optical coupler is described that includes a cavity output coupler mirror, a piezoelectric actuator coupled to the cavity output coupler mirror, a locking assembly within which the cavity output coupler mirror and the piezoelectric actuator are positioned, and one or more components coupled to the locking assembly. The components are configured to provide multiple positional degrees of freedom for tuning a frequency comb spectrum of the pulsed laser (e.g., tuning a repetition rate) by adjusting at least one position of the locking assembly with the cavity output coupler mirror. A method of adjusting an output optical coupler in a pulsed laser is also described. These techniques may be used in different applications, including quantum information processing.

Abstract: The disclosure describes various aspects of a shed-resistant thermal atom source. More specifically, a thermal atom source is described for uniform thermal flux of target atomic species in which a metal wadding material is used as an intermediary surface for sublimation of the atoms, preventing the source material from shedding or dropping. In an aspect, a thermal atom source may include a container with closed and open ends, and inside a source material near the closed end and a wadding between the source material and the open end; a heater coupled to the closed end; one or more clamps configured to secure the container and the heater; and a current source coupled to the container and the heater to cause a temperature to increase such that a portion of the source material is released and diffuses to the open end through the wadding prior to being emitted as a flux.
