A research team has achieved the holy grail of quantum computing: an exponential speedup that’s unconditional. By using ...

Syllabus: The NTA has put the official JEE Main 2026 Syllabus online on their website: jeemain.nta.nic.in. If you're planning ...

Researchers have used the teleportation trick to forge a working logic gate between two separate quantum chips.

Thus the design and realization of the Basic Logic gates and Combinational circuits like ripple carry adder, serial adder, multiplexer are done by using the concept of Quantum Cellular Automata. Also, ...

From theory to hardware. The Oxford team was simply interested in a proof-of-concept, and so used an extremely simplified system. Each end of the 2-meter gap had a single trap holding two ions ...

MIT researchers are developing techniques to make quantum gates, the basic operations of a quantum computer, as fast as possible in order to reduce the impact of decoherence. However, as gates get ...

For example, an AND gate accepts two inputs, each either 0 or 1, and outputs 1 if both inputs are 1 and 0 for any other combination of inputs. A quantum bit, or qubit, has two distinct states ...

Further project successes include significant improvements in the central hardware and software as well as the peripherals for the spin-photon-based quantum computer: The basic material and its ...

Quantum computers act by performing specific operations (called gates) on individual or pairs of qubits; to do that, you have to know exactly which qubit you're addressing.

Artist’s representation of the formation pathway of vacancy complexes for spin-based qubits in in the silicon carbide host lattice and to the right the associated energy landscape. Quantum ...

One can replicate any quantum gate or at least get arbitrarily close to it using enough CNOT, H, X, Z and π/8 rotation gates. The core component of quantum computing hardware, a quantum processing ...

The corresponding operations in quantum computers are implemented by quantum gates, which can be classified depending on the number of qubits involved. As opposed to classical gates, quantum gates can ...
