Recently, there has been remarkable progress towards the development of large-scale quantum devices through advances in quantum science and technology. This progress opens new doors for proof-of-principle demonstrations of quantum simulations as well as practically useful applications, such as quantum-enhanced metrology. However, these applications require first quantifying how well a quantum device produces a desired […]

Surpassing the fundamental limits that govern all electromagnetic structures, such as reciprocity and the delay-bandwidth-size limit, will have a transformative impact on all applications based on electromagnetic circuits and systems. For instance, violating principles of reciprocity enables non-reciprocal components such as isolators and circulators, which find application in full-duplex wireless radios, radar, bio-medical imaging, and […]

The development of computing systems able to address our ever-increasing needs, especially as we reach the end of CMOS transistor scaling, requires truly novel methods of computing. My research draws inspiration from biology, rethinks the digital/analog boundary, and challenges conventional wisdom, which typically guides how we perform computation, by reimagining the role of time. In […]

“Continuous” monitoring of specific biomarkers in real-time offers longitudinal information that can enable not only rapid medical decision-making but also early disease detection. As opposed to the current end-point diagnostics approaches, such a continuous-monitoring capability introduces a new dimension in achieving precision medicine and precision health. In this talk, I will present my research contributions […]

The ability to understand living systems in the body and attain therapeutic effects at target organs promises to transform therapies for complex diseases and conditions that cannot be treated adequately with drug-based therapies alone. The last decade has seen rapid advances in implantable medical devices (implants), ranging from new materials to increased implant sophistication and […]

Learning how to create, study, and manipulate highly entangled states of matter is key to understanding exotic phenomena in condensed matter and high energy physics, as well as to the development of useful quantum computers. In this talk, I will discuss recent experiments where we demonstrated the realization of a quantum spin liquid phase using […]

A photonic-electronic system can potentially process enormous amounts of data that no stand-alone electronics have been capable of. Furthermore, a chip-scale optical atomic clock can be so precise that it only loses the equivalent of one second every million years. In the foreseeable future, highly integrated photonics can usher disruptive advances in communications, deep learning, […]

Many-body quantum systems are the most powerful computers allowed by Nature. How do they work? Can we control them? Are they useful? In this talk, I discuss how recent results in quantum information theory translate into quantum engineering solutions. I introduce a geometric information measure that rigorously evaluates the difference between two complex configurations of arbitrarily […]

As two basic properties of light, wavelength and timescale are central to numerous photonic applications. Compared to visible and near-infrared, the longer wavelength mid-infrared spectral regime contains unique thermal visual information and chemical fingerprints of the environment.  On a different front, femtosecond light sources and systems can enable ultrafast information processing, sensing, and computing. Yet, […]

Stable chronic mapping of brain activities at the action potential level with high temporal resolution is essential for both fundamental neuroscience research and biomedical applications, including cognitive studies, memory encoding and retrieval, and neural prostheses. Conventional neural probes can provide high spatiotemporal-resolution brain signal recordings independent of probing depth, although they generally trigger foreign body […]
