Enlarge / The qubits of the brand new {hardware}: an array of particular person atoms. (credit score: Atom Computing)
Right now, a startup known as Atom Computing introduced that it has been doing inside testing of a 1,180 qubit quantum pc and can be making it accessible to clients subsequent 12 months. The system represents a significant step ahead for the corporate, which had solely constructed one prior system based mostly on impartial atom qubits—a system that operated utilizing solely 100 qubits.
The error charge for particular person qubit operations is excessive sufficient that it will not be doable to run an algorithm that depends on the total qubit depend with out it failing attributable to an error. But it surely does again up the corporate’s claims that its expertise can scale quickly and offers a testbed for work on quantum error correction. And, for smaller algorithms, the corporate says it will merely run a number of cases in parallel to spice up the prospect of returning the precise reply.
Computing with atoms
Atom Computing, as its title implies, has chosen impartial atoms as its qubit of selection (there are different corporations which might be working with ions). These methods depend on a set of lasers that create a sequence of places which might be energetically favorable for atoms. Left on their very own, atoms will are likely to fall into these places and keep there till a stray fuel atom bumps into them and knocks them out.
