Quantifying Coherence with Untrusted Devices

2018 · arXiv (Cornell University)

Device-independent (DI) tests allow to witness and quantify the quantum feature of a system, such as entanglement, without trusting the implementation devices. Although DI test is a powerful tool in many quantum information tasks, it …

Seeds of SEED: H²Cache: Building a Hybrid Randomized Cache Hierarchy for Mitigating Cache Side-Channel Attacks

2021

Cache side-channel attacks can leak critical information from the target programs. The cache randomization methodology has proven to be an efficient way to mitigate such attacks. However, existing works do not take the cache hierarchy …

Entanglement distribution over 155 km metropolitan fiber using a CMOS-compatible silicon chip

2025 · Newton

Transmitting entangled states over long distances is crucial for developing quantum networks. Previous demonstrations using satellites or fibers relied on photon pairs generated from bulk crystal arrangements. Polarization entanglement distribution based on complementary metal-oxide-semiconductor (CMOS)-compatible …
