24 “logical quibits” — the largest number ever. New discovery will accelerate sciences such as chemistry and materials science.
A new one published in November in Quantum Physics has set a new record for quantum entanglement, bringing reliable quantum computers closer to reality, says
The scientists managed to intertwine 24 “logical qubits”— quantum bits Low-error information created by combining multiple physical qubits. This is the highest number ever achieved to date, highlighting the
Unlike the binary 1s and 0s of traditional computer bits, qubits work based on a completely different mechanics — quantum mechanics, to be more precise. Although qubits can exist as 1s and 0s, Live Science emphasizes, they can also exist as both at the same time, a phenomenon known as overlap. This fact makes measuring qubits a greater challenge.
The qubits are still subject to two variables — the coherence and entanglement.
A coherence it is a measure of the time during which qubits maintain the desired state necessary to process quantum calculations. Coherence times are typically measured in fractions of a second and can be disturbed by the smallest environmental factors.
When qubits lose coherence, they often also lose their entanglementmechanism by which the state of one qubit is directly linked to that of another.
Loss of coherence and entanglement negatively affects the capacity of quantum computers to carry out calculations with precision and reliability.
Now, scientists involved in the study have successfully entangled their record-breaking 24 logical qubits using the “neutral atom quantum processor” from Atom Computing, which processes and stores quantum information by manipulating individual atoms with lasers, and the “qubit virtualization system” from Microsoft, a software platform that helps manage and stabilize qubits by detecting and correcting errors in real time.
“Fault-tolerant quantum computing is essential for solving large computational problems that enable a scientific and economic value greater than that of classical computingand requires the integration of multiple advanced technologies and quantum error correction algorithms to provide sufficient reliable computing resources in a sustainable way“, Atom representatives wrote in a .
“With these results, we now demonstrate all the essential ingredients needed to support quantum error correction“, they add.
The researchers also demonstrated how logical qubits are able to perform complex tasks and keep errors in check as quantum computers scale up.
Using the same Atom system, experts created and performed calculations on 28 logical qubitswhich proves that it is possible to maintain error correction at a time when quantum systems become more powerful and complex.
“By coupling our next-generation neutral atom qubits with Microsoft’s qubit virtualization system, we can now deliver reliable logic qubits in a commercial quantum machine,” he wrote Ben Bloomfounder and CEO of Atom Computing, in .
“This system will allow a rapid progress in various domainsincluding chemistry and materials science”, he concluded.
