First company to demonstrate scalable quantum behaviour by integrating qubits with all supporting control and read-out electronics on the same integrated circuit using a commercial silicon process

ucd.ie, May. 13, 2021 – 

Equal1 Laboratories (Equal1), a silicon-based quantum computing company, today announced the company is the first to demonstrate a fully integrated quantum processor unit (QPU) operating at 3.7 kelvin ― a major milestone with implications for the trajectory of quantum computing.

The company is addressing a major challenge for the quantum computing industry of scaling the number of qubits so that a quantum computer can tackle useful, real-world problems. With its QPU, Equal1 has developed a disruptive, scalable and cost-effective quantum computing technology, based on a commercially available silicon semiconductor process.

The QPU employs patented, Equal1-designed, nanometer-scale quantum dots to create qubits (the quantum equivalent to digital bits) on a standard silicon CMOS process. In addition to the silicon qubits, all control and read-out electronics required for a fully functioning QPU are integrated on-chip with over 10 million transistors.

In addition to developing its QPU, Equal1 has designed and manufactured the closed cryogenic and vacuum system, together with the control and communication electronics to maintain the chip at 3.7 K and interface to room temperature.

Due to the operation of the qubits at 3.7 K (referred to as "hot qubits") and the level of integration the team has achieved, the form factor of the quantum demonstrator is far smaller than alternative technologies (rack-sized versus room-sized).

Equal1 was founded by Dirk Leipold, Mike Asker and Professor R. Bogdan Staszewski and is a spin-out from the UCD School of Electrical and Electronic Engineering. The Equal1 team has offices at NovaUCD, the Centre for New Ventures and Entrepreneurs at University College Dublin, and in California.
