The Quantum Innovators workshop will bring together the most promising young researchers in quantum physics and engineering for a three-day conference aimed at exploring the frontier of our field.
Quantum simulation proposes to use future quantum computers to calculate properties of quantum systems. In the context of chemistry, the target is the electronic structure problem: determination of the electronic energy given the nuclear coordinates of a molecule. Since 2006 we have been studying quantum approaches to quantum chemical problems, and such approaches must face the challenges of high, but fixed, precision requirements, and fermion antisymmetry.
The manipulation and detection of individual quantum excitations forms the basis of modern quantum physics experiments. However, most of these experiments have been restricted to systems composed of only a few particles.

Quantized vibrations of the lattice (phonons) are intrinsic to all of condensed- matter physics. Most experimental probes, however, treat the phonons in terms of thermal-equilibrium quantities such as heat capacity and thermal conductance, rather than directly addressing the vibrational quanta. I will discuss two types of experiments employing nanofabricated devices and low-temperature techniques to explore and exploit non-equilibrium phonon behavior.
A fundamental question in complexity theory is how much resource is
needed to solve k independent instances of a problem compared to the
resource required to solve one instance. Suppose solving one instance of
a problem with probability of correctness p, we require c units of some
resource in a given model of computation. A direct sum theorem states
that in order to compute k independent instances of a problem, it

The advantages of single photons make them not only the workhorse of testing the foundations of quantum physics against the classical interpretation of nature, but also suitable for various tasks in quantum information processing. In my talk, I will first present our long-distance quantum teleportation with active feed-forward in real time. This experiment uses both quantum and classical optical links over 143 km free space between the two Canary Islands of La Palma and Tenerife and is a major step towards quantum communication on a global scale.
Localizing arrays of atoms in photonic crystals could provide new capabilities for quantum networks and quantum many-body physics. Intriguing theoretical analyses suggest the emergence of completely new paradigms for strong atom-photon interactions that exploit the tremendous flexibility for modal and dispersion engineering of one and two-dimensional photonic crystals.
