We’re increasingly turning to computers to automate processes in our daily lives. But, computers use electricity and for some functions computers may just not be the best tool. ⚡ Researchers in the group of Martin van Hecke at AMOLF/ Leiden Institute of Physics have used rubber structures to make a system that can count using mechanical forces instead of electricity. 📣 📢 Turnstiles that give people access to buildings or other facilities may in the future be operated using these rubber structures.

Theoretical physicists at Utrecht University, together with experimental physicists at Sogang University in South Korea, have succeeded in building an artificial synapse. This synapse works with water and salt and provides the first evidence that a system using the same medium as our brains can process complex information. The results appeared today in the scientific journal Proceedings of the National Academy of Sciences. Tim Kamsma, a PhD candidate at the Institute for Theoretical Physics and the Mathematical Institute of Utrecht University, and the lead author of the study, expresses his excitement, stating, "While artificial synapses capable of processing complex information already exist based on solid materials, we now show for the first time that this feat can also be accomplished using water and salt." He emphasizes, "We are effectively replicating neuronal behaviour using a system that employs the same medium as the brain."

TLDR: eigenlijk was Niels Bohr een hopeloze filosofische prutser 🤓 On the Relative Nature of Quantum Individuals | by Christian de Ronde et al. | ArXiv In this work we argue against the interpretation that underlies the "Standard" account of Quantum Mechanics (SQM) that was established during the 1930s by Niels Bohr and Paul Dirac. Ever since, following this orthodox narrative, physicists have dogmatically proclaimed -- quite regardless of the deep contradictions and problems -- that the the theory of quanta describes a microscopic realm composed of elementary particles (such as electrons, protons and neutrons) which underly our macroscopic world composed of tables, chairs and dogs. After critically addressing this atomist dogma still present today in contemporary (quantum) physics and philosophy, we present a new understanding of quantum individuals defined as the minimum set of relations within a specific degree of complexity capable to account for all relations within that same degree. In this case, quantum individuality is not conceived in absolute terms but -- instead -- as an objectively relative concept which even though depends of the choice of bases and factorizations remain nonetheless part of the same invariant representation. https://lnkd.in/eMCASmDN #quantum #mechanics #physics #SQM #Copenhagen #interpretation #Bohr #atomism #dogma #elementary #particles #elementaire #deeltjes #individuality #science #philosophy

#Cryptography paper Secure Groups for Threshold Cryptography and Number-Theoretic Multiparty Computation by Berry Schoenmakers and Toon Segers from Department of Mathematics & Computer Science, TU Eindhoven https://lnkd.in/ggSBp4R8 #multiparty #computation; extended gcd; #elliptic curve #cryptography; #class #groups; #threshold cryptography Abstract: In this paper, we introduce secure groups as a cryptographic scheme representing finite groups together with a range of operations, including the group operation, inversion, random sampling, and encoding/decoding maps. We construct secure groups from oblivious group representations combined with cryptographic protocols, implementing the operations securely. We present both generic and specific constructions, in the latter case specifically for number-theoretic groups commonly used in cryptography. These include Schnorr groups (with quadratic residues as a special case), Weierstrass and Edwards elliptic curve groups, and class groups of imaginary quadratic number fields. For concreteness, we develop our protocols in the setting of secure multiparty computation based on Shamir secret sharing over a finite field, abstracted away by formulating our solutions in terms of an arithmetic black box for secure finite field arithmetic or for secure integer arithmetic. Secure finite field arithmetic suffices for many groups, including Schnorr groups and elliptic curve groups. For class groups, we need secure integer arithmetic to implement Shanks’ classical algorithms for the composition of binary quadratic forms, which we will combine with our adaptation of a particular form reduction algorithm due to Agarwal and Frandsen. As a main result of independent interest, we also present an efficient protocol for the secure computation of the extended greatest common divisor. The protocol is based on Bernstein and Yang’s constant-time 2-adic algorithm, which we adapt to work purely over the integers. This yields a much better approach for multiparty computation but raises a new concern about the growth of the Bézout coefficients. By a careful analysis, we are able to prove that the Bézout coefficients in our protocol will never exceed 3max(𝑎,𝑏) in absolute value for inputs a and b. We have integrated secure groups in the Python package MPyC and have implemented threshold ElGamal and threshold DSA in terms of secure groups. We also mention how our results support verifiable multiparty computation, allowing parties to jointly create a publicly verifiable proof of correctness for the results accompanying the results of a secure computation.

How to create porous silicon wafers with a hierarchical pore structure, mimicking those in biological materials less expensive and less limited in scalability. Ehawedry new study written by Manuel Brinker, Patrick Huber, focused on the creation of porous silicon wafers. They combine metal-assisted chemical etching with photolithography to create silicon wafers with both large and small pores. Silver nanoparticles act as catalysts in the process. The resulting wafers have high porosity and are suitable for various applications like energy storage, sensors, and actuators. They can also be transformed into porous silica, useful in opto-fluidic and photonic applications.

📣 Our colleagues Clare Shelley-Egan and Pieter Vermaas, from the Delft University of Technology 'Ethics of Quantum Technology' Research Group, recently published a short editorial in the Journal of Responsible Technology, where they engage with the European Commission's recommendation calling for risk assessment with Member States on four critical technology areas, including quantum technology. 💡 Clare Shelley-Egan: "We argue that potential protectionist approaches can lead to moral isolationism which, in turn, could limit Europe's contribution to global development with respect to technological advances, sustainable development and quality of life". 💡 Pieter Vermaas: "In our group at TU Delft, we conduct research on the ethics of quantum technologies, but it's good to sometimes step out or academia and take position on the topic.” 🧠 As researchers in the Quantum and Society action line of the Dutch quantum ecosystem, Quantum Delta NL, they have an interest in supporting and advancing the responsible development of quantum technologies. In this editorial, they express concerns about the narrow framing of the risk assessment, within the economic and security domains, that represents an unwanted moral isolationism, ignoring other central European Union (EU) values in research and technology development. 🌐 In its recommendation, the European Commission identifies the following four technology areas with the greatest likelihood of posing significant risks as regards technology security and technology leakage. ✔ semiconductor technologies ✔ artificial intelligence technologies ✔ quantum technologies ✔ biotechnologies 🌐 The four critical technology areas were selected according to the following characteristics: ✔ their enabling and transformative nature ✔ the risk of civil and military fusion ✔ the risk of misuse of the technology for human rights violations 🧠 The editorial concludes that while technological protectionism seems inevitable in the contemporary landscape of international relations, it does require careful consideration with respect to its impact on European values. 🔎 Read the full editorial in the link below 👇 https://lnkd.in/eBuPmcYE Quantum Delta NL Diederick Croese Deborah Nas Victor Land Daniël Frijters Dr. Ulrich Mans Joris van Hoboken Vania López Luis Antonio Gómez Pérez María Palacios Thijs Latten #quantum #values #technologydevelopment #ethics
