"Good afternoon, gentlemen. I am a HAL 9000 computer.
I became operational at the H. A. L. lab in Urbana, Illinois
on the 12th of January"
This sound is enconded on an 18 qubit quantum computer and it is recovered with a finite number of quantum measurments performed in time or frequency domain (MP3 like) in presence of gate imperfections.
We can also listen the sound of a complex quantum wavefunction generated by an efficient quantum algorithm (14 qubits).
Quantum computations are done
on Quantium I simulated numerically on Pentium IV.
