In quantum
mechanics, the dimension of the Hilbert space grows exponentially with system
size. Therefore, a classical calculation of many-body quantum states becomes
practically impossible for a small number of particles. Richard Feynman was the
first to suggest a different paradigm to overcome this difficulty, a quantum
computational machine (“quantum computer”). The quest to build a quantum
computer has been going on for more than 20 years, but so far, no single
experimental platform has emerged as technologically superior. I present our
suggestion for a new platform based on ultracold fermionic atoms held in an
optical microtrap. In our scheme, quantum information can be stored in the
internal states of these atoms or in vibrational states of the trap. Single
qubit gates are implemented by coupling the atom to an external field, and a
universal two-qubit
gate is implemented by a novel
protocol that takes advantage of our ability to precisely control the
tunnelling energy and the interaction energy (by using Feshbach resonance)
between two atoms at two adjacent traps. I present numerical simulations of the
qubits and gates and report on our progress in the lab towards testing our
ideas in real life.
