A new study on quantum computing reports a record of quantum entanglement, proving that we are well on our way to post-NISQ (noisy intermediate-scale quantum) computing. The new research, led by Xiao-bo Zhu of the University of Science and Technology of China, has successfully unentangled a record 51 qubits (the quantum computing equivalent of transistors). This is the power needed to unlock probabilistic quantum computing, a quantitative leap in human processing power.
Zuchongzhi, the quantum computer used to achieve the experimental results, contains 66 superconducting qubits. This is the same qubit technology backed by IBM and many other major players in the quantum computing space. This is the same technology that IBM recently achieved quantum utility through its 127-qubit Eagle QPU (quantum processing unit), and various parties have confirmed that there is a special life happening in the superconducting qubit space. introduced from
After cooling the superconducting qubit to absolute zero in space (-273.15 degrees Celsius, -459.67 degrees Celsius), Fahrenheit), the researchers then used microwaves to control and fine-tune the state of the qubits. The microwave interacted with the qubit’s magnetic field to manipulate the qubit into a state of quantum entanglement. This was necessary so that the qubits would be organized in specific sequences (or logic gates), the quantum equivalent structures built from transistors to form CPU cores in standard computing. This allows scientists to perform operations that change the state of many pairs of qubits at once, rather than just one-to-one connection fields. With these techniques, scientists have successfully entangled 51 qubits (arranged in a row) and his low but record 30 qubits arranged in a two-dimensional plane.
Charles Hill, a researcher at the University of New South Wales in Australia, is perhaps one of the better scientists to comment on this result. Hill was involved in a similar study, aiming to prove a similar “networked” entanglement between 65 qubits.
Entanglement is, perhaps, qubits arranged in such a way that a single qubit cannot be explained without being able to explain all other qubits and how they are related to each other. Best understood to mean to intertwine. This is essentially a unique system, a knot without dangling. thread.
In a comment provided to New Scientist, Hill explained entanglement: Demonstrating mass quantum entanglement will be an important benchmark for quantum computers. ”
At the time of his work, Hill’s team had not succeeded in proving extended entanglement not only between linked pairs, but also between qubits as a group. This was the same validation difficulty that Zhu encountered (and overcame) with his Zuchongzhi QPU.
Relatively often, we develop new tools and new ways to observe objects, or interactions between objects. In this case, the problem Hill encountered in his 65-qubit entanglement experiment may have had nothing to do with entanglement itself. The techniques that were probably available to validate his results simply failed to provide a convincing response. Zhu’s team had to develop a new detection protocol to verify swarm entanglement, which is sure to be thoroughly scrutinized by the quantum computing community. After all, it’s not every day that promises of entangling hundreds of qubits surface.
The entanglement group of qubits is one of many intermediate research opportunities pursued by quantum scientists, in an attempt to increase computational fidelity through error mitigation and possibly quantum error correction, to find out how noise is affected. leading to the discovery of clever ways of predicting how to destroy a qubit, effectively nullifying its effect.
At 51 entanglements, it is not expected to break through the quantum dominance barrier, at least until scaling takes a little longer. But now that IBM has recently shown that utility can already be extracted from modern quantum computers, 51 entangled qubits could unlock a realm of possibilities given the answers we don’t even know the question of yet. never leave.
