Abstract: A quantum computer based on electrons floating over liquid helium is described. Each qubit is made of combinations of ground and first excited states of an electron trapped over micro-electrodes just below the helium surface. We describe mechanisms for preparing the initial state of the qubit, operations with the qubits, and a proposed readout. This system is, in principle, capable of \sim 104 operations in a decoherence time, the time in which the wave function collapses.
Key Words: Quantum computing, Decoherence, Electrons on helium
