Abstract
There is provided a method for transmitting a quantum state, performed by a computing device. The method may comprise generating a second quantum state using a first quantum state and a dummy state, encoding the second quantum state, generating a third quantum state by injecting an uncorrectable error into the encoded second quantum state and transmitting the third quantum state to a receiving node.
Claims20
A method for transmitting a quantum state, performed by a computing device, comprising:
- generating a second quantum state using a first quantum state and a dummy state;
- encoding the second quantum state;
- generating a third quantum state by injecting an uncorrectable error into the encoded second quantum state;
- and
- transmitting the third quantum state to a receiving node.
A method for verifying a quantum state, performed by a computing device, comprising:
- receiving a quantum state from a transmitting node;
- receiving an uncorrectable error from the transmitting node;
- obtaining a first syndrome by applying the uncorrectable error to the quantum state;
- and
- performing a first verification process on the quantum state by determining whether the obtained first syndrome matches a predetermined second syndrome.
A computing system comprising:
- at least one processor;
- and
- a memory storing a computer program executed by the at least one processor,
- wherein the computer program includes instructions to perform operations of:
- generating a second quantum state using a first quantum state and a dummy state;
- encoding the second quantum state;
- generating a third quantum state by injecting an uncorrectable error into the encoded second quantum state;
- and transmitting the third quantum state to a receiving node.
