We use the polynomial method to prove optimal or nearly optimal lower bounds on the quantum query complexity of several problems, resolving open questions from prior work. The problems studied include k-distinctness, image size testing, k-junta testing, approximating statistical distance, approximating Shannon entropy, and surjectivity. Paper available at https://arxiv.org/abs/1710.09079. This is joint work with Mark Bun and Justin Thaler.
Researchers and early-stage companies may discover numerous investment options on their path to commercial success. While some mechanisms focus on a certain phase of technology development, others promise to fuel growth over a wide R,D&D spectrum, possibly independent of prior investment status. This panel covers a sampling of programs and investment strategies - from technology scouting to angel capital - for mobilizing intellectual property towards impactful deployment.

This presentation will delve into a practical example of a patent procedure associated to a specific quantum technology: a vectorial magnetometer. We will explore the specifics of the technology and its applications, review previously existing approaches and define the inventive step, explore the phrasing of the claims, and revisit the prior patents from the freedom-to-operate point of view.
If you’ve ever wished you could escape this world for another Universe, the winner of this year’s Quantum Shorts flash fiction competition offers a cautionary tale.
In “Acceptable Loss” by Przemysław Zańko, a failed relationship puts the entire multiverse under threat. The story is one of five to claim prizes in the competition for fiction inspired by quantum physics. Each winner receives a cash award, certificate, and an engraved trophy.

Sensors based on quantum effects can measure various external quantities, such as magnetic fields, with high precision. Moreover, their sensitivity can scale more favourably with their size than is allowed classically — a property analogous to quantum speedups in computing. As with quantum computers, the performance of quantum sensors is limited by decoherence. Quantum error correction (QEC) has recently emerged as a promising approach to mitigate this decoherence, and therefore, to enhance sensitivity.
Xiaodong Ma: Topological insulator and the quantum anomalous Hall effectThe quantum anomalous Hall effect (QAHE) is defined as a quantized Hall effect in a system without an external magnetic field. Its physical origin relies on the intrinsic topological inverted band structure and ferromagnetism.
