Private Product Computation using Quantum Entanglement. (arXiv:2305.05993v1 [quant-ph])
cs.CR updates on arXiv.org arxiv.org
In this work, we show that a pair of entangled qubits can be used to compute
a product privately. More precisely, two participants with a private input from
a finite field can perform local operations on a shared, Bell-like quantum
state, and when these qubits are later sent to a third participant, the third
participant can determine the product of the inputs, but without learning more
about the individual inputs. We give a concrete way to realize this product
computation …
