A group of researchers were able to accurately manipulate “over 6,100 neutral atoms via a matrix of optical tweezers.”
The experiment, published on Nature Magazine on September 24th, Scalability of quantum systemsone of the main challenges regarding quantum computing development.
According to the report, the technique used consisted of catching atoms using an optical matrix (known as “optical tweezers”) at approximately 12,000 different locations.
Optical tweezers are rays that can capture and manipulate small particles such as atoms and molecules. In the context of this research, they allow the atom to be organized and moved. It was as if they were fragments of a boardcreate qubits that can interact with each other.
This type of arrangement has recently established itself as one of the most promising platforms for atomic physics and quantum computing.
Previously, similar works were said in the report, although without consistent control, even some systems with around 1,000 atoms could control dozens or hundreds of atomic qubits (a type of ulna).
In this case, the researcher not only climbed the number of particles (6,100 neutral atoms), but They have reached a metric that is considered essential Quantum computer survival rate.
These are some of those metrics:
- The system reached a coherence time of 12.6 seconds. This is a record of hyperfin qubits (called in English) Hyper Fin) With this type of arrangement.
- It had a useful life of atom confinement of approximately 23 minutes at room temperature.
- Survival rates during observation were 99,98952%, and image loyalty was above 99.99%.
These numbers reflect advances in both stability and accuracy. These are two factors that are usually technical obstacles on the way to quantum practical use.
How to correct quantum errors
One point that researchers stand out is that this experiment lays the foundation for SO-CALLED’s “universal quantum computing,” specifically error correction (QEC).
Current test systems usually handle dozens of qubits, but they produce results Not enough to implement the fix scheme This allows you to run complex algorithms.
This study also raises a zone-based computer model. This takes advantage of the ability to transport qubits without inconsistency.
In the test, scientists performed an operation of collecting and ejecting atoms at large spatial distances, Maintains the quality of quantum information.
According to the authors, these results suggest that, along with other recent advances in the field, it is possible in the short term to have thousands or tens of thousands of physical qubits.
The Vision of Quantum Computer Specialists
Leeor Mushin’s observation is a co-founder of Project Eleven, adding to the vision that quantum computing is Close to integration Although it looked like it a few years ago.
«A year ago, emotions were far more bassist, but now they happen faster than most people think. Not tomorrow, but soon,” Mushin said. In his words, he refers to the sector, which, after some “fake auroras,” began to show signs of concrete maturation.
Mushin also highlighted important differences regarding artificial intelligence. Quantum does not have its own replicable model, but infrastructure addresses a variety of difficult physical principles that move between businesses.
“As an investor, you can do the right thing about quantum, but if you choose a superconductor qubit instead of a neutral atom, for example, you could lose,” he explained.
Project Eleven is an applied laboratory for developers and engineers focusing on the intersection of quantum computing and encryption. Its main mission is to protect digital assets such as Bitcoin and cryptocurrency from potential quantum threats that can be used to undermine safety.
