2. 1. Representation of Quantum Algorithms with Symbolic Language and Simulation on Classical Computer

   Author : Peter Nyman; Andrei khrennikov; Paul Fischer; Växjö universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Deutsch-Josza algorithm; Grover s algorithm; Quantum computing; Quantum error-correcting; Shor s algorithm; Simon s algorithm; Simulation of quantum algorithms; Deutsch-Josza algoritm; Grovers algoritm; Kvantdatorer; kvantmekanisk felrättande kod; Shors algoritm; Simons algoritm; Simulering av kvantdatorer; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

   Abstract : Utvecklandet av kvantdatorn är ett ytterst lovande projekt som kombinerar teoretisk och experimental kvantfysik, matematik, teori om kvantinformation och datalogi. Under första steget i utvecklandet av kvantdatorn låg huvudintresset på att skapa några algoritmer med framtida tillämpningar, klargöra grundläggande frågor och utveckla en experimentell teknologi för en leksakskvantdator som verkar på några kvantbitar.

   Abstract : In this thesis we study quantum-like representation and simulation of quantum algorithms by using classical computers.The quantum--like representation algorithm (QLRA) was  introduced by A. Khrennikov (1997) to solve the ``inverse Born's rule problem'', i.e. READ MORE

5. 3. Correlation spectroscopy with epitaxial quantum dots : Single-photons alone in the dark

   Author : Lucas Schweickert; Val Zwiller; Klaus D. Jöns; Richard J. Warburton; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum dots; single--photons; indistinguishability; entanglement; Optik och fotonik; Optics and Photonics;

   Abstract : The advent of quantum computation promises exciting advances, not only in fields like medicine and metrology, but many industries that rely on parameter-heavy calculations or simulation of molecular interaction. At the same time Shor's algorithm for quantum computers presents a threat to current asymmetric encryption protocols used in everyday communication. READ MORE

6. 4. Using Coding Techniques for Attacking Post-Quantum Cryptographic Assumptions and Systems

   Author : Qian Guo; Institutionen för elektro- och informationsteknik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Post-quantum cryptography for resisting possible attacks from malicious quantum adversaries has become one of the key topics in recent cryptographic research. Its ultimate goal is to search for efficient and secure primitives replacing the factoring- and discrete log-based schemes in service that will be broken in polynomial time by Shor’s algorithm.

7. 5. Decryption Failure Attacks on Post-Quantum Cryptography

   Author : Alexander Nilsson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-quantum cryptography; Code-based cryptography; Lattice-based cryptography; side-channel attack;

   Abstract : This dissertation discusses mainly new cryptanalytical results related to issues of securely implementing the next generation of asymmetric cryptography, or Public-Key Cryptography (PKC).PKC, as it has been deployed until today, depends heavily on the integer factorization and the discrete logarithm problems.
