Quantum Circuits Opens Lab for Modular Quantum Computers

Quantum Circuits (QCI) is using superconducting qubits in a modular, robust, and scalable architecture. They are a spinout from Yale University.

QCI’s unique software platform harnesses the power of our quantum hardware. We are building a full stack of flexible software to run novel and complex algorithms, exploiting the full potential of quantum computation.

Delivering Quantum as a Service.

QCI opened its New Haven development and testing facility for quantum computing.

The facility includes 6,000 square feet of state-of-the-art laboratories and in-house manufacturing. It will house more than 20 scientists and engineers.

Late in 2017, they announced raising $18 million.

They have published work on quantum modules and teleportation of gates.

Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the “teleportation” of a quantum gate between two qubits, on demand.

The key principle behind this new work is quantum teleportation, a unique feature of quantum mechanics that has previously been used to transmit unknown quantum states between two parties without physically sending the state itself. Using a theoretical protocol developed in the 1990s, Yale researchers experimentally demonstrated a quantum operation, or “gate,” without relying on any direct interaction. Gates are necessary for quantum computation that relies on networks of separate quantum systems — an architecture that many researchers say can offset the errors that are inherent in quantum computing processors.

Error resistance would be a key feature until error-corrected quantum computers are made. Error-corrected quantum computers need 1000 times as many qubits as non-error corrected quantum computers.
