“One of the first really important thi ngs to demonstrate was these repeated rounds of quantum error correction cycles,” Ryan-Anderson added. This combination provides for outstanding, first – of – its – kind achievements that help accelerate the entire industry,” Tony Uttley, president and COO of Quantinuum, said.Ĭiaran Ryan – Anderson, a senior advanced physicist at Quantinuum, said the newest research paper builds on prior research, which demonstrated the application of multiple rounds of quantum error correction to a single logical qubit. “Quantinuum’s trapped – ion quantum computing roadmap is designed around continuous upgrades, enabled our flexible architecture and our precision control capabilities. The design of these computers offer the flexibility to improve and to adapt to the fast-advancing nature of quantum information science. The experiment was carried out on the H1-1 and H1-2 trapped-ion quantum computers. The two codes were implemented on different but similar devices, and in both instances, all of the quantum error correction primitives, including the determination of corrections via decod ing, are implemented during runtime using a classical compute environment that is tightly integrated with the quantum processor, according to the post. In the second instance, a 20-qubit trapped-ion quantum computer was used to implement a transversal logical CNOT gate on two logical qubits. Logical CNOT gate between two logical qubits using the quantum error correction code. In the first instance, they used a 12-qubit trapped-ion quantum computer to implement a non-transversal In the study, the researchers characterized and compared two different implementations of fault-tolerant entangling gates on logical qubits. “The most promising candidate was this quantum error correction, where we take the physical qubits, make a log ical qubit.” “ It becomes very difficult to suppress noise to very small levels, and that becomes a problem in quantum computing, ” she said. M ost classical error correction principles fail with quantum comput ers because of the basic nature of quantum mechanics, said Natalie Brown, an advanced physicist at Quantinuum. Tying too many qubits on error-correction tasks saps the real power of quantum computers. The team explains that logical qubits are groups of physical qubits working together to perform a computation while other qubits are performing tasks such as spotting and correcting errors. However, because of the delicate nature of quantum operations, error-correction is absolutely essential to create quantum devices that can perform calculations for practical applications. The first demonstration of a logical entangling circuit that has higher fidelity than the corresponding physical circuit.Īll forms of of technology require error-correction, according to the researchers.The first demonstration of entangling gates between two logical qubits done in a fully fault-tolerant manner using real-time error correction.In a handful of firsts, the company’s scientists report the study specifically shows: An important next step for us is to get the error rate induced by the error correction itself down further.” “T he other thing that’s new here is that in other experiments we’re doing the error correction while we’re doing the operations. “People have worked with error corrected qubits b efore, but they haven’t reached this sort of special point where the encoded operation is working better than the primitive operation,” Hayes said. The demonstration offers a path toward scalability, qubit efficiency and less circuitry needed for fault-tolerance, the team added.ĭavid Hayes, a theory and architecture technical manager at Quantinuum, said in a company blog post that the research moves quantum computing closer to the point where encoded circuits outperform more primitive operations. It’s also an achievement that only recently was thought to be years away. A team of Quantinuum scientists report on an important research advance that shows logical qubits can outperform physical qubits, a key step toward quantum computers that can be used to solve practical problems.
