Parametric Amplifiers

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

Advance Information

Available Q2 of 2022

Millimeter Wave Systems, LLC, working with University of Massachusetts Boston and with support from the National Science Foundation’s SBIR program, has developed a 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 travelling 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 expected Q3 of 2021.
