Abstract
Methods, systems and computer readable media are disclosed for providing a quantum cipher based on phase inversion, A shared key is established between a first party and a second party. A Hadamard transformation is applied to a message intended for a second party from the first party to produce an equal superposition state. A key phase inversion is applied to the output of the Hadamard transformation. A multiple phase inversion transformation is applied to the output of the key phase inversion to produce an encrypted quantum state with a uniform probability and relative phase distributions. The result is sent to the second party.

A method of providing a quantum cipher based on phase inversion, the method comprising:
- establishing a shared key between a first party and a second party;
- applying a Hadamard transformation to a message intended for a second party from the first party to produce an equal superposition state;
- applying a key phase inversion to the output of the Hadamard transformation;
- applying a multiple phase inversion transformation to the output of the key phase inversion to produce an encrypted quantum state with a uniform probability and relative phase distributions;
- and
- sending the result to the second party.
A system comprising:
- a UE including a first quantum computing element;
- and
- a core network including a second quantum computing element;
- wherein the first quantum computing element provides a quantum cipher based on phase inversion for a message sent from the UE to the core network;
- wherein the second quantum computing element provides a quantum cipher based on phase inversion for a message sent from the core network to the UE, wherein the quantum cipher based on phase inversion is provided by the method comprising:
- establishing a shared key between a first party and a second party:
- applying a Hadamard transformation to a message intended for a second party from the first party to produce an equal superposition state;
- applying a key phase inversion to the output of the Hadamard transformation;
- applying a multiple phase inversion transformation to the output of the key phase inversion to produce an encrypted quantum state with a uniform probability and relative phase distributions;
- and sending the result to the second party.
A non-transitory computer-readable medium containing instructions which,
- when executed, cause a quantum computing element to perform steps comprising:
- establishing a shared key between a first party and a second party;
- applying a Hadamard transformation to a message intended for a second party from the first party to produce an equal superposition state;
- applying a key phase inversion to the output of the Hadamard transformation;
- applying a multiple phase inversion transformation to the output of the key phase inversion to produce an encrypted quantum state with a uniform probability and relative phase distributions;
- and
- sending the result to the second party.
