Maximising the efficiency of a quantum circuit is of great interest to scientists from around the world, and researchers at the Indian Institute of Science (IISc) Bengaluru have now addressed this ...

The 2-qubit gate realizes the interaction between the two qubits by acting on the states of the two qubits, thereby constructing a quantum circuit and realizing quantum computing.

Quantum computing is now within reach, thanks to a major breakthrough in which scientists demonstrate that a key building block of quantum computers, a quantum Fredkin gate, can be assembled.

In this paper, the authors show design of quantum ternary equality, less-than, and greater-than comparators on the top of ion-trap realizable 1-qutrit gates and 2-qutrit Muthukrishnan-Stroud gates.

This research not only addresses several long-standing challenges in quantum circuit design but also paves the way for the ... to overcome key obstacles such as multiple controlled-X gates, amplitude ...

Researchers have developed a new quantum circuit design that could reduce energy consumption in computing by up to 51%.

Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists created an atomic circuit that may help quantum computing become a reality.

The reduction in circuit depth is critical for achieving practical quantum machine learning on current devices, which are often limited by gate fidelity and qubit count.
