Quantum Computing Notes

2018-12-11T06:25:21+01:00Dicembre 23rd, 2017|Quantum Computing|

Quantum Computing Notes Quantum computing exploits quantum behaviors, such as superposition and entanglement, to perform computations; it is thanks to these behaviors that NP-hard problems can be solved in a reasonable time (NP-hard problems are combinatorial in nature, their solution involves the determination of optimal combinations). It must be [...]
