a supercomputer follows calculations like a normal computer, but these are not calculated by a single computer but by a large, interconnected system. Such a system consists of
Quantum computers can be emulated on classical computers, but the results are slow and impractical for normal use. The vectors needed to simulate the movement and size of a qubit can be quite large, and performing a single computational step requires multiplying every vector. Because of this, cl...
Unlike a normal computer bit, which can be either 0 or 1, a qubit can exist in a multidimensional state. The power of quantum computers grows exponentially with more qubits. Classical computers that add more bits can increase power only linearly. ...

Quantum computing is an exciting new field of research that has begun in recent years to yield practical processing devices. Quantum mechanics is the branch of physics that applies at the microscopic sub-atomic level. Here, the normal laws of physics that govern how we live no longer apply, ...
Classical computers are well suited for everyday use in normal environments. Consider something as simple as a standard laptop: Most people can take one out of their briefcase and use it in an air-conditioned café or outside on a sunny summer day. In such environments, the performance o...
different role, supplying a needed energy uncertainty that then allows a choice to be made between the separated space–time geometries, rather than providing an actual energy that enters into any considerations of energy balance that would be of direct relevance to chemical or normal physical ...
Hyper-parallel photonic quantum computation with coupled quantum dots Bao-Cang Ren* & Fu-Guo Deng* Department of Physics, Applied Optics Beijing Area Major Laboratory, Beijing Normal University, Beijing 100875, China. It is well known that a parallel quantum computer is more powerful than a ...
Another interesting approach towards the realization of MZMs in topological superconductors (TSC) is the fractional Josephson effect, which has a 4π-periodic current-phase relationship (CPR) rather than the normal 2π-periodicity3,12. This effect was first predicted by Kitaev for an ideal 1D spi...
We present a direct comparison between QAOA (Quantum Alternating Operator Ansatz), and QA (Quantum Annealing) on 127 qubit problem instances. QAOA with p = 1, 2 rounds is executed on the 127 qubit heavy-hex graph gate-model quantum computer ibm_
