Google Unveils 72-Qubit Quantum Processor

Google Quantum AI lab has revealed the Bristlecone, another quantum processor. Exhibited at the American Physical Society meeting in Los Angeles, the PC chip hit a record-setting energy of 72 quantum bits (qubits).

“The purpose of this gate-based superconducting system is to provide a testbed for research into system error rates and scalability of our qubit technology, as well as applications in quantum simulation, optimization, and machine learning,”says Julian Kelly, Research Scientist, Quantum AI Lab.

Conventional PCs store

Conventional PCs store information as twofold digits (bits). They are spoken to as either a one or zero. Quantum machines use quantum bits (qubits), which can exist in various states immediately, unfathomably expanding pace and execution.

One test that faces quantum PCs is blunder rates. Quantum bits are as yet shaky, and any clamor can cause mistakes. In any case, the Google framework "exhibited low mistake rates for readout (1 percent), single-qubit doors (0.1 percent) and in particular two-qubit entryways (0.6 percent)" as its best outcome on a 9-qubit gadget.

The team is looking to translate the 9-qubit tech results across all 72 qubits of Bristlecone. With such a feat ahead, the team remains confident.

“We are cautiously optimistic that quantum supremacy can be achieved with Bristlecone, and feel that learning to build and operate devices at this level of performance is an exciting challenge,” Kelly says.

Quantum computers are very attractive concepts, since a single binary digit of information, known as a qubit, can exist in a state of superposition of “0” or “1.” Taking on two forms simultaneously and entangling multiple qubits together vastly increases a quantum computer’s potential power.

"It's extremely exciting. You can use this unique feature of the measurement-based model of quantum computing—the way information flows through the state—as a crypto tool to hide information from the server," says Tommaso Demarie, CQT, SUTD, and team member of the research.
