By Lov K. Grover, April 01, 2001

Quantum computers can be in multiple states and carry out multiple computations at the same time and the quantum search algorithm Lov presents here takes advantage of that characteristic.
Apr01: Searching with Quantum Computers 


r = qrandom(4,0); 
if (f(r) == 1)  invert_phase(); 
r = qrandom(4,r); 
if (r==0)       invert_phase(); 
r = qrandom(4,r); 
print(r);
