Scientists innovate first quantum processor at Yale University

On Sunday, a team of Yale University researchers has innovated first solid-state quantum processor that may break current cryptography system,quantum systems easily in forthcoming years. It will speedup the search for solutions for some mathematical problems.

They’ve also used a two-qubit superconducting chip to run elementary algorithms like simple search, demonstrating quantum information processing with a solid-state device for the first time ever. Each qubit has been composed of billions of aluminum atoms. Qubits are different from bit that can hold a value 1 or 0 as on or off. Traditional bit can also hold a superposition of both states this means the qubit can hold 4 simultaneous states. 

The team member, Robert Schoelkopf said that “Our processor can only a few very simple quantum tasks, which have been demonstrated before with single nuclei, atoms and photons” while William A. Norton Professor of Applied Physics and Physics at Yale stated “But this is the first time they’ve been possible in an all-electronic device that looks and feels much more like a regular microprocessor”.

The qubit processor is communicating via a quantum bus which send signals by photons that transfer the information through wires connecting the qubits. This kind of computations looks simple but it haven’t been possible using solid-state qubits till now because scientists couldn’t get the qubits to last longer than nanosecond. So next the team is working to extend the quantity of time to maintain the qubit states so that they can run more complex algorithms. They are also planing to work to connect more qubits to the bus.

So this is the ultimate work done by Yale University for the future, which will provide advantage of the manufacturing process that will be developed for the microprocessors. “We’re still far away from building a practical quantum computer, but this is a major step forward,” said Schoelkopf.
