Quantum computing systems, apparatus, and methods

A transceiver may include a transmit path and a receive path that are each coupled to a radio frequency (RF) interface, and a self-interference canceller (SIC). The SIC is coupled between the transmit and the receive paths. The SIC is configured to cancel a self-interference signal from a received signal on the receive path based on a transmit signal on the transmit path.

An apparatus can include a digital-to-analog converter (DAC) and calibration circuitry including an oscillator. The calibration circuitry can be coupled to an output of the DAC, the calibration circuitry to sample and count DAC output pulses for at least two consecutive pulses using at least two separate counter circuits. The calibration circuitry can determine error between at least two consecutive pulses and provide a correction value based on the error. The apparatus can further include correction circuitry to provide a calibration signal to the DAC based on the correction value.

Technologies for radiofrequency optimized interconnects for a quantum processor are disclosed. In the illustrative embodiment, signals are carried in coplanar waveguides on a surface of a quantum processor die. A ground ring surrounds the signals and is connected to the ground conductors of each coplanar waveguide. Wire bonds connect the ground ring to a ground of a circuit board. The wire bonds provide both an electrical connection from the quantum processor die to the circuit board as well as increased thermal coupling between the quantum processor die and the circuit board, increasing cooling of the quantum processor die.

Technologies for on-circuit board de-embedding are disclosed. In the illustrative embodiment, several micromechanical relays on a circuit board can connect a trace on the circuit board to an open circuit, a closed circuit, a load circuit, or a through circuit. For the through circuit, the trace is connected to an integrated circuit component mounted on the circuit board. A cable is connected to the trace, allowing for signals to be sent to any of the four circuits without any probes connected to the circuit board. The transmitted and/or reflected signals can be measured, which can be used to de-embed the integrated circuit component.

Radar apparatus, system, and method

An array of quantum dot qubits (e.g., an array of spin qubits) relies on a gradient magnetic field to ensure that the qubits are separated in frequency in order to be individually addressable. Furthermore, a strong magnetic field gradient is required to electrically drive the electric dipole spin resonance (EDSR) of the qubits. Quantum dot devices disclosed herein use microcoil arrangements for providing a gradient magnetic field, the microcoil arrangements integrated on the same chip (e.g., on the same die or wafer) as quantum dot qubits themselves. Unlike previous approaches to quantum dot formation and manipulation, various embodiments of the quantum dot devices disclosed herein may enable improved control over magnetic fields and their gradients to realize better frequency targeting of individual qubits, help minimize adverse effects of charge noise on qubit decoherence and provide good scalability in the number of quantum dots included in the device.

The capacitors in the array of capacitors are connected to the gate one at a time, charging up a parasitic capacitance. As more capacitors are switched, the voltage on the gate approaches a target voltage with an exponentially-decreasing voltage error.
