"This suggests that there is no additional fundamental limitation in realizing a dual-type entangling gate, such that it can be applied in practical quantum circuits to help reduce the overhead of ...

A new proposal makes the case that paraparticles—a new category of quantum particle—could be created in exotic materials.

emphasizes the importance of accurate benchmarking of gate errors. "What's unique about our approach is that it can clearly distinguish between different types of quantum errors," Levenson-Falk said.

Silicon spin qubits could soon help unlock the next stage of quantum computing. For decades, scientists have tried to harness the power of quantum mechanics to perform calculations beyond the reach of ...

Researchers have developed a new protocol for characterizing quantum gate errors, paving the way toward more reliable quantum simulations and fault-tolerant quantum computing. Researchers have ...

Quantum gates are inherently different from binary ... it can be hard to compare the capabilities of different types of quantum processors. The development of quantum processors still faces ...

The gate-based approach is based on sequential ... This will inspire entirely new types of quantum computers, some of which may even be based on newly discovered quantum principles.

Another type of bug comes from qubit initialization errors. That happens when qubits are not put into their initial state correctly. One more issue is gate fidelity errors. Quantum gates may not ...

The system has been tested using several different types of quantum processor and it could ... processing (such as sending messages over a network) with quantum operations (such as executing gates or ...

The quantum gate teleportation process may seem like a ... While the work was done with trapped ions, almost every type of qubit in development can be controlled with photons, so the general ...

Researchers have developed a new protocol for benchmarking quantum gates, a critical step toward realizing the full potential of quantum computing and potentially accelerating progress toward ...
