Future graduate students

Robert F. McDermott, University of Wisconsin, Madison

One of the remarkable recent discoveries in information science is that quantum mechanics can lead to efficient solutions for problems that are intractable on conventional classical computers.

Applications of the trilinear Hamiltonian with three trapped ions

Roland Esteban Hablützel Marrero, Centre for Quantum Technologies, National University of Singapore

Three coupled harmonic oscillators with an interaction given by the trilinear Hamiltonian $a^{\dagger} b c + a b^{\dagger} c^{\dagger}$ can describe a wide range of physical processes. In this talk I will show how we implement the trilinear Hamiltonian utilizing a chain of three $^{171}$Yb$^+$ ions in a linear Paul trap.

Colloquium: Zhengcheng Gu, The Chinese University of Hong Kong

Searching for p+ip topological superconducting (SC) state has become a fascinating subject in condensed matter physics, as a dream application awaits in topological quantum computation. In this talk, I will report the theoretical discovery of a p+ip SC ground state (coexisting with ferromagnetic order) in honeycomb lattice Hubbard model with infinite repulsive interaction at low doping(< 0.2), by using both the state-of-art Grassmann tensor product state(GTPS) approach and a quantum field theory approach.

Shaping photons on-demand

Experiment finds way to increase photon efficiency for quantum communications

A team of researchers at the Institute for Quantum Computing (IQC) demonstrated a new type of on-demand single photon generator that can shape photons to increase their efficiency when used in a quantum network.

Next-generation communication networks will rely on the transmission of quantum information. Single photons, as carriers of quantum information, will play an integral role in building these future networks.

The Institute for Quantum Computing is pleased to announce a call for entries to the Quantum Shorts flash fiction competition. The competition is open to stories up to 1000 words long that take inspiration from quantum physics and include the phrase “There are only two possibilities: yes or no”. The competition is free to enter, offering prizes of up to US $1500.
