QCamp

Date/Time: 10-Jun - 14-Jun
Venue: CQT Level 3 Seminar Room S15-03-15

QCamp is a one-week summer school for curious pre-university students who wish to explore and understand the physical laws that govern the world's smallest scales: quantum physics. The scope of QCamp is to provide vivid demonstrations of these laws, offer career advice, as well as to help students build a technical foundation for independent exploration of this world. QCamp is organised by the Centre for Quantum Technologies (CQT) at the National University of Singapore.

1-day flash QCamp

Date/Time: 19-Jun - 19-Jun
Venue: LT 34

Since CQT’s five-day QCamp for pre-university students is typically oversubscribed, this year we are pleased to offer a separate one-day flash QCamp. The camp is for curious and inquisitive minds to get a taster in quantum technologies. It will feature talks, demos and career advice.

Title: Generation of high-quality polarization-entangled photons with a silicon chip
Date/Time: 27-May, 12:30PM
Venue: CQT Level 3 Conference Room, S15-03-17

Abstract:Silicon photonics is a promising platform that is compatible withCMOS technology, offering advantages in miniaturization, simplicity offabrication, and the potential for mass production. However, on-chippolarization-entangled photon sources (essential components for quantuminformation processing and quantum computing) is very challenging to make. Onereason is silicon waveguides support only Transverse Electric (TE) modes,whereas polarization entanglement typically requires both TE and Transverse Magnetic(TM) modes. Additionally, collecting quantum lights from silicon chips withoptical fibers are always lossy, result in low observed brightness. In thistalk, I will discuss our recent breakthroughs in optimizing the overall system,employing novel, low-loss edge couplers. These have enabled us to develop asilicon-based polarization-entangled photon source with ultra-high observedbrightness comparable to that of traditional bulk crystal sources.

Title: Thinking Inside The Box: Privacy Against Stronger Adversaries
Date/Time: 20-May, 02:00PM
Venue: CQT Level 3 Conference Room, S15-03-17

Abstract:Cryptography is the study of protocols between multiple parties that provide privacy against adversaries. However, the typical guarantee of such protocols is only against adversaries who access is limited to information disclosed publicly by the protocols themselves. Such adversaries are referred to as ``black-box adversaries''. Real life adversaries might perform real life attacks like being able to obtain leakage information via a side-channel, or the ability to tamper with memory, or install backdoors. In this work, we study cryptographic primitives against these ``in-the-box'' adversaries and show the following: (1) Leakage-resilient secret sharing, and non-malleable secret sharing requires extractable randomness; (2) there exist 2-source non-malleable extractors that match Raz's two source extractor in the asymptotic min-entropy rate requirement; (3) A recent construction by Guo et al. for immunizing one-way functions based on the hardness of 3SUM enjoys various privacy guarantees against pre-processing adversaries.
