Abstract: | |||||
Quantum mechanics predicts phenomena which have no classical analogue. This
modifies our understanding of the capability of physical machines. Single photons,
together with simple interferometers and single photon detection, have been shown
to be universal for the construction of many such machines. The nascent field
of integrated quantum photonics addresses the scalability and practicality of such
machines, and their integration in miniaturized monolithic chips.
In this work, we explore the scope and flexibility afforded by integrated quan- .
tum photonics, both in terms of practical problem-solving, and for the pursuit of
fundamental science. We demonstrate and fully characterize a two-qubit quantum
photonic chip, capable of arbitrary two-qubit state preparation. We make use of the
unprecedented degree of reconfigurablility afforded by this device to implement a
novel variation on Wheeler's delayed choice experiment, and test a new technique to
obtain nonlocal statistics without a shared reference frame. We demonstrate a new
algorithm for quantum chemistry, simulating the helium hydride ion. Finally, we
demonstrate multiphoton quantum interference in a large Hilbert space, and discuss
implications for computational complexity.
