发帖数: 115 | 1 is there any process which you know of which forbids the following
circumstance:
You prepare 4 qubits: 1,2,3,4
qubit 1 and 2 are in a maximally entangled state such that they are
electrons with opposite spins.
qubit 3 and 4 are in a maximally entangled state such that they are
electrons with opposite spins.
# (symbol) = Psi
* = a marker to denote spin
thus:
#(1,2) = (1*)(2) + (1)(2*)
#(3,4) = (3*)(4) + (3)(4*)
or
#(1,2,3,4) = (1*)(2)(3*)(4) + (1)(2*)(3)(4*) + (1*)(2)(3)(4*) +
(1)(2*)(3*)(4*)
