Kavli Affiliate: Birgitta Whaley | First 5 Authors: Neel R. Vora, Yilun Xu, Akel Hashim, Neelay Fruitwala, Ho Nam Nguyen | Summary: Similar to reading the transistor state in classical computers, identifying the quantum bit (qubit) state is a fundamental operation to translate quantum information. However, identifying quantum state has been the slowest and most […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: D. O. Oriekhov, Guliuxin Jin, Eliska Greplova, , | Summary: It is well-known that quantum algorithms such as Grover’s can provide a quadradic speed-up for unstructured search problems. By adding topological structure to a search problem, we show that it is possible to achieve a constant search-time […]
Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, , , , | Summary: We explore the universal signatures of quantum phase transitions that can be extracted with the density matrix renormalization group (DMRG) algorithm applied to quantum chains with a gradient. We present high-quality data collapses for the order parameter and for the […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Sameer Sonar, Utku Hatipoglu, Srujan Meesala, David Lake, Hengjiang Ren | Summary: Optomechanical crystals (OMCs) enable coherent interactions between optical photons and microwave acoustic phonons, and represent a platform for implementing quantum transduction between microwave and optical signals. Optical absorption-induced thermal noise at cryogenic (millikelvin) temperatures is […]
Kavli Affiliate: Lihong V. Wang | First 5 Authors: Yang Zhang, Joshua Olick-Gibson, Karteekeya Sastry, Lihong V. Wang, | Summary: Optical imaging of blood flow yields critical functional insights into the circulatory system, but its clinical implementation has typically been limited to shallow depths (~1 millimeter) due to light scattering in biological tissue. Here, we […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Shreyansh Pitroda, Aditya Bondada, Kaushik Venkatesh Krishnamurthy, Adarsh Salagame, Chenghao Wang | Summary: Despite major advancements in control design that are robust to unplanned disturbances, bipedal robots are still susceptible to falling over and struggle to negotiate rough terrains. By utilizing thrusters in our bipedal robot, we […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Neelay Fruitwala, Akel Hashim, Abhi D. Rajagopala, Yilun Xu, Jordan Hines | Summary: Randomized compiling (RC) is an efficient method for tailoring arbitrary Markovian errors into stochastic Pauli channels. However, the standard procedure for implementing the protocol in software comes with a large experimental overhead — namely, […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Zhawnen Chen, Tianchun Wang, Yizhou Wang, Michal Kosinski, Xiang Zhang | Summary: Can large multimodal models have a human-like ability for emotional and social reasoning, and if so, how does it work? Recent research has discovered emergent theory-of-mind (ToM) reasoning capabilities in large language models (LLMs). LLMs […]
Kavli Affiliate: Birgitta Whaley | First 5 Authors: Yipei Zhang, Philippe Lewalle, K. Birgitta Whaley, , | Summary: We generalize the projection-based quantum measurement-driven $k$-SAT algorithm of Benjamin, Zhao, and Fitzsimons (BZF, arxiv:1711.02687) to arbitrary strength quantum measurements, including the limit of continuous monitoring. In doing so, we clarify that this algorithm is a particular […]
Kavli Affiliate: James J. Bock | First 5 Authors: Matthew A. Petroff, Zeeshan Ahmed, James J. Bock, Marion Dierickx, Sofia Fatigoni | Summary: The search for the polarized imprint of primordial gravitational waves in the cosmic microwave background (CMB) as direct evidence of cosmic inflation requires exquisite sensitivity and control over systematics. The next-generation CMB-S4 […]
