Quantum Computation

Quantum computers, which harness the power of quantum superposition and entanglement, have the potential to perform calculations well beyond what is possible with foreseeable classical computers. However, building a functioning quantum computer is extremely difficult, because it requires highly accurate manupulation of  a large number of interconnected but fragile quantum states. We experimentally investigate solid-state devices based on the spin of individual electrons with long coherence times, which makes them natural candidates for building large-scale universal quantum computers.

Quantum Simulators

Quantum simulators are special purpose quantum information systems that can be used to mimic other less controllable quantum systems. They are anticipated to be among the first technological applications in quantum information science, to help design materials or chemical processes, and to enable laboratory tests of exotic aspects of many-body quantum theory that go beyond what which can be tested in traditional experiments. We are experimentally investigating quantum simulators based on the spin and charge interactions in semiconductor quantum dots.
