Apparatus and method including scalable representations of arbitrary quantum computing rotations

A method comprising:

• decoding a plurality of instructions;
• executing a first instruction or set of the instructions to generate a floating point (FP) value and to store the FP value in a first register;
• executing a second instruction or set of the instructions to read the FP value from the first register and compress the FP value to generate a compressed FP value having a precision selected for performing quantum rotation operations;
• and
• processing the compressed FP value to cause a quantum rotation to be performed on one or more qubits of a quantum processor.

A non-transitory machine-readable medium having program code stored thereon which, when executed by a machine, causes the machine to perform operations of:

• decoding a plurality of instructions;
• executing a first instruction or set of instructions to generate a floating point (FP) value and to store the FP value in a first register;
• executing a second instruction or set of instructions to read the FP value from the first register and compress the FP value to generate a compressed FP value having a precision selected for performing quantum rotation operations;
• and
• processing the compressed FP value to cause a quantum rotation to be performed on one or more qubits of a quantum processor.
