2 New Processor Adds to Quantum Computing Ecosystem: IBM

IBM on Friday announced 20-qubit and 50-qubit quantum processors for its IBM Q early-access commercial systems.

The 20-qubit processor, featuring improvements in superconducting qubit design, connectivity and packaging — has coherence times of 90 microseconds, which allows high-fidelity quantum operations, IBM said.

The 50-qubit processor is an operational prototype. It expands upon the 20-qubit architecture and has similar performance metrics.

IBM will offer these quantum processors as a service.

Clients will have online access to the first IBM Q systems with the 20-qubit processor by the end of this year.

The company declined to specify when the 50-qubit processor will be available as a service, IBM Research spokesperson Christine Vu told the E-Commerce Times.

During 2018, IBM plans to improve the quality of qubits in the 20-qubit processor, as well as circuit connectivity and operation error rates.

A 20-qubit processor “would enable very large computing problems [such as] cryptography protein interactions, chemical interactions and flow simulations,” said Michael Jude, research manager at Stratecast/Frost & Sullivan.

“Essentially, it would enable the solution of many systems of nonlinear differential equations,” he told the E-Commerce Times. TechNewsWorld

IPhone X users complain about Earpiece Speaker

IPhone X users have started complaining a buzzing sound from its earpiece speaker. The issue reportedly becomes noticeable at higher volume levels and isn’t resolved even with replacement units.

Some of the affected users have reported the earpiece issue of the iPhone X on Reddit and Twitter, as well as explain its existence in the comments section on 9to5Mac. The users report that a sound similar to rattling or clipping emerges from the speaker. “It seems to be rattling/clipping when playing anything at high volume, even if it’s just someone talking. I even got my phone replaced yesterday, but the new unit has the same issue,” one of the users writes on in a Reddit thread.
