Query: Quantum Interference Induced Photon Blockade in a Coupled Single Quantum
  Dot-Cavity System   We propose an experimental scheme to implement a strong photon blockade with
a single quantum dot coupled to a nanocavity. The photon blockade effect can be
tremendously enhanced by driving the cavity and the quantum dot simultaneously
with two classical laser fields. This enhancement of photon blockade is
ascribed to the quantum interference effect to avoid two-photon excitation of
the cavity field. Comparing with Jaynes-Cummings model, the second-order
correlation function at zero time delay $g^{(2)}(0)$ in our scheme can be
reduced by two orders of magnitude and the system sustains a large intracavity
photon number. A red (blue) cavity-light detuning asymmetry for photon quantum
statistics with bunching or antibunching characteristics is also observed. The
photon blockade effect has a controllable flexibility by tuning the relative
phase between the two pumping laser fields and the Rabi coupling strength
between the quantum dot and the pumping field. Moreover, the photon blockade
scheme based on quantum interference mechanism does not require a strong
coupling strength between the cavity and the quantum dot, even with the pure
dephasing of the system. This simple proposal provides an effective way for
potential applications in solid state quantum computation and quantum
information processing.
