Quantum-Limited Multi-Qubit Amplifiers (MQAs™) for Quantum Information Systems

Advance Information
Available 2023
Millimeter Wave Systems, LLC, working with the University of Massachusetts Boston and with support from the National Science Foundation’s SBIR program, has developed an MQA™ (Multi-Qubit Amplifier) capable of amplifying the outputs to detectable levels of more than fifty quantum bits (qubits) with a single quantum-limited amplifier. The outputs, also known as readouts, represent the results from quantum computer computations. When used with a multiplexed readout scheme, this technology will enable higher-density quantum computers by reducing the hardware size, complexity, and heat load over single qubit solutions. The MQA™ is supplied with a quantum noise-limited cryogenic traveling wave parametric amplifier (TWPA) and a turn-key controller unit that includes pump sources and various accessories to ensure quick setup and system optimization. Commercial availability is expected 2023.
