|Title||QUANTUM PROGRAM CONCEALING DEVICE AND QUANTUM PROGRAM CONCEALING METHOD|
An object of the present invention is to enable an authorized user to execute a quantum program, without letting the authorized user know the operation contents of the quantum program. A quantum program concealment device 10 includes an expansion unit 12 that generates an expanded quantum program that includes an inputted quantum program and has a quantum secret key quantum bit space corresponding to a quantum secret key in addition to an input quantum bit space of the quantum program, a control operation addition unit 13 that rewrites the expanded quantum program so as to perform a control operation that executes a quantum program in a case where the quantum secret key quantum bit space is in a predetermined state, an encryption unit 15 that adds, to the expanded quantum program,
a first quantum gate array and a second quantum gate array for performing operations with respect to a state of the quantum secret key quantum bit space, a secret key generation unit 16 that generates a quantum secret key by performing an inverse operation of the first quantum gate array, and an obfuscation unit 17 that performs obfuscation with respect to the expanded quantum program to which the first quantum gate array has been added.
