They created the first programmable quantum logic processor that will help in medicine and other fields

Harvard physicists They created the first Quantum logical processor Programmable, capable of coding up to 48 logical qubits And perform hundreds of logic gate operations.

Published in the journal Nature, which is A major turning point In search of a computing Quantum technology is stable and scalable, a Very high speed Which will allow Revolutionary progress The university said in a statement, in a variety of fields, including medicine, science and finance.

The system is the first show to implement Extensive algorithms On a quantum computer with Correct mistakesheralds the arrival of early fault-tolerant or reliably uninterrupted quantum computing.

Professor Mikhail Lukin, who led the research, described: completion As a potential turning point similar to the early days in the field artificial intelligence: Correction ideas Quantum errors Fault tolerance, long a theoretical topic, is beginning to bear fruit.

I think this is one of those moments where it becomes clear that something very special is coming. Although there are still challenges ahead, we hope that this new breakthrough will accelerate progress toward useful, large-scale quantum computers.

Lukin said in a statement.

In the Quantitative statisticsA quantum bit, or qubit, is a unit of… Information, just like the binary bit in classical computing. For more than two decades, physicists and engineers have shown the world just that Quantitative statistics It is, in principle, possible through manipulation of quantum particles (be they… AtomsOr ions or photons) to create physical qubits.

But exploited successfully The weirdness of quantum mechanics Because computing is more complex than just compiling a Enough amount A large number of qubits, which are inherently unstable and prone to collapsing out of their quantum states.

The real ones'Kingdom coins“These are so-called logical qubits: bundles of redundant, error-correcting physical qubits that can… Store information For use in quantum algorithm.

the Creating logical qubits As controllable units (such as classical bits) have been a fundamental barrier to the field, it is generally accepted that even Quantum computers If it could work reliably with logical qubits, the technology wouldn't really be able to take off.

Until now, Best computer systems They have been shown to contain one or two logical qubits and a quantum gate process (similar to a single code unit) between them.

The Harvard team's progress depends on several factors Years of work In the quantum computing architecture known as Atom matrix Neutralizers, created by the Lukin Laboratory.

he Main ingredient The system is a block of Rubidium atoms Ultracold is suspended, where atoms (the system's physical qubits) can move and connect in pairs (or “entangle”) in the middle of a computation.

the Pairs of atoms Interwoven they form the doors, which are Power units computing. Previously, the team showed low error rates in interleaving operations, which indicates… Reliability of your system Matrix of neutral atoms.

With him Quantum processor Logically, researchers now prove He controls Parallel multiplication of an entire patch of logical qubits, using lasers. this The result is more efficient And scalable instead of having to control individual physical qubits.

he The team will continue to work To explain more types of operations on 48 logical bits and configure your system so Run continuouslyinstead of cycling manually as you do now.
