Quantum Oracles in Terms of Universal Gate Set
Yuji Tanaka, Tsubasa Ichikawa, Masahito Tada-Umezaki +2
We present a systematic construction of quantum circuits implementing Grover's database search algorithm for arbitrary number of targets. We introduce a new operator which flips th…
Authorized quantum computation
Yu Tanaka, Mio Murao
We present authorized quantum computation, where only a user with a non-cloneable quantum authorization key can perform a unitary operation created by an authenticated programmer.…
Exact Non-identity check is NQP-complete
Yu Tanaka
We define a problem "exact non-identity check": Given a classical description of a quantum circuit with an ancilla system, determine whether it is strictly equivalent to the identi…
Local encoding of classical information onto quantum states
Yu Tanaka, Damian Markham, Mio Murao
In this article we investigate the possibility of encoding classical information onto multipartite quantum states in the distant laboratory framework. We show that for all states g…
