Atom Computing Claims to Test a 1,180 Qubit Quantum Computer
Atom Computing, a startup in the quantum computing field, has made a bold claim that they are currently testing a 1,180 qubit quantum computer. This would make their system more powerful than those of industry giants like IBM and Google. Their previous system operated with only 100 qubits, so this is a significant leap forward.
A Quantum Leap in Qubit Count
To put things into perspective, IBM’s most powerful quantum computer, the Osprey, has 433 qubits. They are also working on their upcoming Condor model that will have 1121 qubits. Google’s Sycamore has 70 qubits. Atom Computing’s use of neutral atoms as qubits promises stability and scalability.
Precise Placement and Manipulation
Atom Computing uses lasers to precisely place and manipulate neutral atoms on a grid. They store quantum data in the atom’s nuclear spin, which is less affected by environmental distractions. This allows for longer and uninterrupted performance.
Expanding the Grid for More Advancements
Atom Computing has expanded their grid from a 10×10 setup to an impressive 35×35. This expansion offers even more potential for quantum advancements.
The Challenge of High Error Rates
While Atom Computing’s system boasts an impressive number of qubits, the error rate for individual qubit operations is very high. This makes it impractical for complex calculations at the moment. However, Atom Computing expects to solve this issue in the near future and achieve fault-tolerant quantum computing.
Parallelizing Computation with Identical Qubits
Atom Computing plans to use all their qubits in parallel to speed up computation. If given a 50-qubit algorithm, they will perform it on all their qubits and provide faster results.
Neutral Atoms vs. Ions
Both neutral atoms and ions are being explored as potential qubits in quantum computing. While ion-based systems have made progress, neutral atoms offer a promising alternative with the potential for rapid scaling.
The Future of Quantum Computing
If Atom Computing succeeds, we may have a future with scalable and reliable quantum computers. IBM, another major player in the field, is also working towards a 100,000-qubit quantum computer.
Hot Take: The Race for Efficiency and Reliability in Quantum Computing
Atom Computing’s claim of testing a 1,180 qubit quantum computer represents a significant advancement. However, it’s important to manage expectations as the quantum realm still faces challenges. The efficiency and reliability of these systems will ultimately determine the leaders in this race.
