IonQ claims it has built the most powerful quantum computer yet – TechCrunch

IonQ Trap Tests

Trapped-ion quantum computing startup IonQ right now introduced the launch of its newest quantum laptop, which options what IonQ calls “32 good qubits with low gate errors.”

Utilizing IBM’s most popular quantum benchmark, IonQ expects to hit a quantum quantity of 4,000,000. That’s an enormous improve over the double-digit quantum volume numbers that IBM itself lately announced and it’s a reasonably extraordinary declare on IonQ’s aspect as this might make its system essentially the most highly effective quantum laptop but.

The (well-funded) firm has by no means used this metric earlier than. Via a spokesperson, IonQ additionally famous that it doesn’t essentially assume quantum quantity is the most effective metric, however since the remainder of the business is utilizing it, it determined to launch this quantity. The corporate argues that its capability to realize 99.9% constancy between qubits has allowed it to realize this breakthrough.

“In a single era of {hardware}, we went from 11 to 32 qubits, and extra importantly, improved the constancy required to make use of all 32 qubits,” mentioned IonQ CEO and president Peter Chapman. “Relying on the appliance, clients will want someplace between 80 and 150 very excessive constancy qubits and logic gates to see quantum benefit. Our aim is to double or extra the variety of qubits annually. With two new generations of {hardware} already within the works, firms not working with quantum now are vulnerable to falling behind.”

It’s value noting that IonQ’s trapped-ion strategy is sort of completely different from IBM’s (or D-Wave’s for that matter) which makes use of a really completely different approach. That makes it arduous to match uncooked qubit counts between completely different distributors. The quantum quantity metric is supposed to make it simpler to match these methods, nevertheless.

“The brand new system we’re deploying right now is ready to do issues no different quantum laptop has been capable of obtain, and much more importantly, we all know the best way to proceed making these methods way more highly effective shifting ahead,” mentioned IonQ Co-Founder & Chief Scientist Chris Monroe. “With our new IonQ system, we anticipate to have the ability to encode a number of qubits to tolerate errors, the holy grail for scaling quantum computer systems within the lengthy haul.”

Utilizing new error correction strategies, IonQ believes that it’s going to solely want 13 qubits to create a “near-perfect” logical qubit.

For now, IonQ’s new system might be out there as a personal beta and it’ll be attention-grabbing to see if its early customers will again up the corporate’s claims. Later, the corporate will make it out there by companions like Amazon with its Braket service and the Microsoft Azure Quantum Cloud.
