"Spin and Qubit Entropy<https://events.seas.harvard.edu/event/spin_and_qubit_entropy>" Abstract: Quantum physics, in its current formulation, is time reversible. We propose a definition of quantum entropy for the spin and the qubit variables, accounting for the uncertainty in the specification of a quantum state and the probabilistic nature of its observables. It is rooted in the geometric quantization of the spin. This entropy overcomes the limitations of previously-proposed entropies, such as von Neumann entropy which is restricted to quantify the randomness of specifying the quantum state. As an example of a limitation, previously-proposed entropies are higher for Bell entangled spin states than for disentangled spin states, even though the spin observables are less constrained for a disentangled pair of spins than for an entangled pair. The proposed entropy accurately quantifies the randomness of a spin or a qubit state, it is lower for entangled states than for disentangled states, and its minimum is positive. We suggest that the proposed entropy must always increase over time, so that the randomness of a closed physical system cannot be reduced, thus creating a time arrow for quantum physics.

He is also a CoFounder of Kooick.ai and Nhega.com. He received the BS in Physics at PUC Rio de Janeiro, Brasil the Ph.D in Physics and Artificial Intelligence at MIT with Professor Tomaso Poggio.

[Harvard-quantum-initiative] Harvard Quantum Information Meeting

by Xun Gao

Dear all, This week will be the fifth "Harvard Quantum Information Group Meeting", which will be held on Thursday, October 27th at 4:30 pm in Jefferson 250. This week, Chinmay Nirke from IBM will talk about the complexity of quantum proofs. Title: Classical oracle separations between QMA and QCMA (joint work with Anand Natarajan, MIT) Abstract: It is a long-standing open question in quantum complexity theory whether the definition of non-deterministic quantum computation requires quantum witnesses (QMA) or if classical witnesses suffice (QCMA). We make progress on this question by constructing a randomized classical oracle separating the respective computational complexity classes. Previous separations [Aaronson-Kuperberg, Fefferman-Kimmel] required a quantum unitary oracle. The separating problem is deciding whether a distribution supported on regular un-directed graphs either consists of multiple connected components (yes instances) or consists of one expanding connected component (no instances) where the graph is given in an adjacency-list format by the oracle. Therefore, the oracle is a distribution over n-bit boolean functions. In this talk, I will give a more pedagogical introduction to the subject – including how to think about the complexity of quantum proofs. Questions are welcome, especially from audience members unfamiliar with the area! Here is the link of <https://calendar.google.com/calendar/u/0?cid=Y185MWI0YjdkMWE3YmJjYzkwODNlNT…>google calenda <https://calendar.google.com/calendar/u/0?cid=Y185MWI0YjdkMWE3YmJjYzkwODNlNT…>r for the next few meetings. The meeting is open to everyone at Harvard interested in quantum information, including those in condensed matter physics, AMO physics, high energy physics, computer science, chemistry, etc. The format includes weekly tutorials (by both external and internal speakers) of contemporary topics in quantum information and quantum computing, aimed for a broad scientific audience. We will also try to foster connections between different groups at Harvard which are interested in or involved with quantum information, and build a broader community. Hope to see you all there. If you would like to join the mailing list for this meeting, please e-mail harvardqimeeting(a)gmail.com <mailto:harvardqimeeting@gmail.com> which will add you.

[Harvard-quantum-initiative] Harvard Quantum Information Meeting

by Xun Gao

Dear all, This week will be the fourth "Harvard Quantum Information Group Meeting", which will be held on Thursday, October 20th at 4:30 pm in Jefferson 250. This week, Roy Garcia from Prof. Arthur Jaffe’s group will talk. Title: Resource theory of quantum scrambling Abstract: Quantum scrambling refers to the spread of local quantum information into the many degrees of freedom of a quantum system. In this work, we introduce a resource theory of scrambling which incorporates two mechanisms, "entanglement scrambling" and "magic scrambling". We introduce two resource monotones called the Pauli growth and the OTOC (out-of-time-ordered correlator) magic for these two mechanisms, respectively. We use our resource theory to explain recent experimental observations of magic. We also show that both resource monotones can be used to bound the decoding fidelity in Yoshida's black hole decoding protocol. These applications provide an operational interpretation of the resource monotones defined in this work.

Special Seminar - Prof. Jason Cong, Friday, Oct. 14, 2022; Science and Engineering Complex - SEC 2.118

by Harvard Quantum Initiative

Special Seminar - Prof. Jason Cong, Distinguished Professor, UCLA Computer Science Department Friday, Oct. 14, 2022 1:00 PM - 2:00 PM, Science and Engineering Complex Room: SEC 2.118 Attend In-person or on Zoom<https://harvard.zoom.us/j/93115310667?pwd=UWpKNVQ0OFlvSllDS1cxYzFzMk92Zz09> Democratizing IC Designs and Customized Computing As we enter the era of customized computing, where customized domain-specific accelerators (DSAs) are used extensively for performance and energy efficiency. Ideally, we would like to enable every programmer should offload the compute-intensive portion of his/her program to one or a set of DSAs, either pre-implemented in ASICs or synthesized on demand on programmable fabrics, such as FPGAs. But integrated circuit (IC) designs remain a black art to many. High-level synthesis (HLS) made an important progress in simplify IC designs, but it still requires the programmer to provide various pragmas, such as loop unroll, pipelining, and tiling, to define the microarchitecture of the accelerator, which is a challenging task to most software programmer. In this talk, we present our latest research on automated accelerator synthesis and customized computing on FPGAs, ranging from microarchitecture guided optimization, such as automated generation of highly optimized systolic arrays and stencil computation engines, to more general source-to-source transformation based on graph-based neural networks and meta learning, and finally to latency-insensitive system-level integration. Speaker Bio: JASON CONG is the Volgenau Chair for Engineering Excellence Professor at the UCLA Computer Science Department (and a former department chair), with joint appointment from the Electrical and Computer Engineering Department. He is the director of Center for Domain-Specific Computing (CDSC) and the director of VLSI Architecture, Synthesis, and Technology (VAST) Laboratory. Dr. Cong’s research interests include novel architectures and compilation for customizable computing, synthesis of VLSI circuits and systems, and highly scalable algorithms. He has over 500 publications in these areas, including 16 best paper awards, and three papers in the FPGA and Reconfigurable Computing Hall of Fame. He and his former students co-founded AutoESL, which developed the most widely used high-level synthesis tool for FPGAs (renamed to Vivado HLS after Xilinx’s acquisition). He was elected to an IEEE Fellow in 2000, ACM Fellow in 2008, the National Academy of Engineering in 2017, and the National Academy of Inventors in 2020. He is the recipient of the 2022 IEEE Robert Noyce Medal for fundamental contributions to electronic design automation and FPGA design methods.
