Finding a short element gg of a number field, given the ideal generated by gg, is a classic problem in computational algebraic number theory. Solving this problem recovers the private key in cryptosys...
Quantum computers are largely hypothetical devices that could perform some calculations much more rapidly than conventional computers can. Instead of the bits of classical computation, which can repre...
On Shor's Factoring Algorithm with More Registers and the Problem to Certify Quantum Computers
Shor’s factoring algorithm quantum register entanglement
2016/1/7
Shor’s factoring algorithm uses two quantum registers. By introducing
more registers we show that the measured numbers in these registers which are of the
same pre-measurement state, should be equal...
