Den här skriften handlar om ljus och ljusets betydelse för oss människor. Tolv forskare med vitt skilda bakgrunder samlas och diskuterar frågor som skrider över gränserna. Vad är ljus egentligen? Hur kan vi förstå ljus? Hur påverkar det oss? På vilket sätt kan vi använda oss av det? Vilka tekniska möjligheter har vi att skapa och styra olika sorters ljus? Vilka möjligheter ger det o

Astrobiologi kallar vi det vetenskapliga sökandet efter liv i rymden som görs av den jordbundna varelsen Homo sapiens sapiens och som utförs på en vanlig planet kring en vanlig sol bland miljarder andra stjärnor och galaxer. Under hennes i universellt perspektiv korta historia på jorden har hon ofta, när hon blickat upp på den stjärnbeströdda natthimlen, undrat över de grundläggande existentiella

En Advanced Study Group (ASG) är en flexibel mötesform för tvärvetenskaplig forskning där forskare från olika discipliner och fakulteter vid Lunds universitet får möjlighet att arbeta tillsammans kring ett gemensamt forskningsproblem som befinner sig i ett mycket tidigt skede. Pufendorfinstitutet bjuder varje år in forskare vid Lunds universitet att föreslå vetenskapliga problemområden, som lämpar

Frågor kring tillit i det digitala, tycks det, ställs oftare och oftare: Hur ska vi hantera integritets- och övervakningsfrågor? Hur ska vi hantera den mätbarhet som följer av vår digitaliserade tillvaro? Vad är det som avgör vilka tjänster vi litar på och vilka vi inte litar på, i vilken mån spelar den tekniska säkerheten en roll? Liknande frågor kan ställas om vilka kunskapsinstitutioner vi lita

Scope The birth and development of quantum physics is one of the main scientific achievements of the 20th century. It has led to a revolution in our understanding of almost all aspects of the world around us and forms the basis of essentially all modern physics and chemistry. Advances in quantum physics have also directly or indirectly been responsible for some of the most important technological

Speaker: Heike Riel Classical computers which represent information as bits have evolved over many years in an unprecedented way and became ubiquitous in our life. Today these classical technologies based on miniaturization are reaching their limits and new computing paradigms are in quest to reduce power consumption and increase the performance of computation. Two new computing paradigms are emer

Speaker: Michelle Simmons The realisation of a large-scale error corrected quantum computer relies on our ability to reproducibly manufacture qubits that are fast, highly coherent, controllable and stable. The promise of achieving this in a highly manufacturable platform such as silicon requires a deep understanding of the materials issues that impact device operation. In this talk I will demonstr

Speaker: Charles Marcus This talk will examine phase control in hybrid semiconductor superconductor materials, including frustration in periodic arrays, phase bias in planar Josephson junctions, and fluxoid quantization in full-shell nanowires. When phase can induce topological superconductivity is discussed and demonstrated.

Speaker: Masahito Ueda Information thermodynamics incorporates quantum measurement into thermodynamics, thereby enabling one to evaluate the cost of measurement and that of information erasure in information processing of thermodynamics [1]. The total cost of measurement and information erasure resolves the paradox of Maxwell’s demon. Information thermodynamics also unifies the modern fluctuation

Speaker: Alexia Auffèves Quantum technologies are currently the object of high expectations from governments and private companies, as they hold the promise to shape safer and faster ways to extract, exchange, and treat information. However, despite its major potential impact for industry and society, the question of their energetic footprint has remained in a blind spot of current deployment stra

Speaker: Alain Aspect Einstein's conclusion that quantum mechanics is not complete was based on a local realist worldview. After Bell's theorem and subsequent experiments, one must renounce local realism. I will argue that non-local quantum images can yield fruitful intuitions.

Speaker: Jörg Wrachtrup Spins in wide band gap semiconductors are a leading contender in various areas of quantum technology. Most notably they have been established as a novel tool for nanoscale sensing, major hardware for long distance quantum entanglement, as well as small scale quantum registers for quantum computing. I will present the use of spins in in those areas [1,2,3]. Specifically, I w

Speaker: Artur Ekert Among those who make a living from the science of secrecy, worry and paranoia are just signs of professionalism. Can we protect our secrets against those who wield superior technological powers? Can we trust those who provide us with tools for protection? Can we even trust ourselves, our own freedom of choice? Recent developments in quantum cryptography show that some of these

Speaker: Nicolas Gisin Quantum information science emerged from studies on the foundations of quantum physics. I’ll illustrate this, starting from Bell inequalities all the way to commercial Quantum Key Distribution and Quantum Random Number Generator chips. But the story doesn’t stop here. Quantum information science, in turn, feeds back into the foundations, asking questions like, e.g., “how doe

Speaker: Steve Girvin This talk will present an overview of systems comprised of both qubits and oscillators. Such hybrid platforms offer powerful architectures with novel gates and instruction sets for quantum computation and hardware-efficient quantum error correction now going beyond the break-even point. In addition, recent experiments on quantum simulations of physical models containing boson

Speaker: John Martinis In order to specify a quantum computer technology, it is important to describe not just the qubit type and architecture, but qubit errors.  This is because qubits are fundamentally error-prone, and computational power can only occur if the errors are small enough, roughly 2%.  I will describe how the quantum supremacy experiment from Google was able to measure system error r

Speaker: Chris Monroe Trapped atomic ions are a leading physical platform for quantum computers, featuring qubits with essentially infinite idle coherence times and the highest purity quantum gate operations. Such atomic clock qubits are controlled with laser beams, allowing densely-connected and reconfigurable universal gate sets. The path to scale involves concrete architectural paths based on w

Speaker: Matthias Steffen How do we deal with errors in quantum mechanics? We trade resources measured in the form of complexity, number of qubits, and runtime for reduced impact of errors. Quantum Error Correction (QEC) generally trades number of qubits and runtime along with classical processing (syndrome matching) to reduce effective errors rates. Owing to the significant overhead associated wi

Speaker: John Preskill I will review an experimentally feasible procedure for converting a quantum state into a succinct classical description of the state, its classical shadow. Classical shadows can be applied to predict efficiently many properties of interest, including expectation values of local observables and few-body correlation functions. Efficient classical machine learning algorithms us
