Implementing a quantum approximate optimization algorithm on a 53-qubit NISQ device
A large team of researchers working with Google Inc. and affiliated with a host of institutions in the U.S., one in Germany and one in the Netherlands has implemented a quantum approximate optimization algorithm (QAOA) on a 53-qubit noisy intermediate-scale quantum (NISQ) device. In their paper published in the journal Nature Physics,, the group describes their method of studying the performance…
Important milestone in the creation of a quantum computer
Quantum computer: One of the obstacles for progress in the quest for a working quantum computer has been that the working devices that go into a quantum computer and perform the actual calculations, the qubits, have hitherto been made by universities and in small numbers. But in recent years, a pan-European collaboration, in partnership with French microelectronics leader CEA-Leti, has been…
Scientists create quietest semiconductor quantum bits on record
Researchers at UNSW Sydney have demonstrated the lowest noise level on record for a semiconductor quantum bit, or qubit. The research was published in Advanced Materials. …
D-Wave announces launch of new Advantage quantum computer for business use
Canadian based D-Wave has announced on its blog that it has developed a new quantum computer for use by businesses. Called Advantage, the new system has 5,000 qubits and 15-way qubit connectivity. The new machine will be made available to business customers over the Internet via the Leap quantum cloud service. …
D-Wave’s 5,000-Qubit Quantum Computing Platform Handles 1 Million Variables
D-Wave today launched its next-generation quantum computing platform available via its Leap quantum cloud service. The company calls Advantage “the first quantum computer built for business.” In that vein, D-Wave today also debuted Launch, a jump-start program for businesses that want to begin building hybrid quantum applications. From a report: “The Advantage quantum computer is the first quantum computer designed and…
IBM Publishes its Quantum Roadmap, Says it Will Have a 1,000-qubit Machine in 2023
IBM today, for the first time, published its road map for the future of its quantum computing hardware. There is a lot to digest here, but the most important news in the short term is that the company believes it is on its way to building a quantum processor with more than 1,000 qubits — and somewhere between 10 and 50…
Xanadu Launches Quantum Cloud Platform, Plans To Double Qubits Every 6 Months
Earlier today, quantum computing startup Xanadu launched its quantum cloud platform, where developers can access the company’s gate-based photonic quantum processors with 8-qubit or 12-qubit chips, with 24-qubit chips coming “in the next month of so.” “The startup expects to ‘roughly double’ the number of qubits available in its cloud every six months,” reports VentureBeat. “The hope is Xanadu Quantum Cloud…
Cosmic rays may soon stymie quantum computing
The practicality of quantum computing hangs on the integrity of the quantum bit, or qubit. …
Researchers on a path to build powerful and practical quantum computer
For the first time, researchers have designed a fully connected 32-qubit trapped-ion quantum computer register operating at cryogenic temperatures. The new system represents an important step toward developing practical quantum computers. …
