  2. 1. For a Fistful of Qubits: Computational Quantum Chemistry on Near-Term Quantum Computers

    Author : Mårten Skogh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonadiabatic processes; quantum error mitigation; variational quantum algorithms; quantum computation; computational chemistry;

    Abstract : Quantum computing has been touted as a great new frontier of computation, pushing the limits of what we consider within reach of computation. While not all problems are expected to be efficiently solved by a quantum computer, quantum chemistry is among those where many have speculated on near-term quantum advantage. READ MORE

  4. 2. Realistic prospect for continuous variable quantum computing in circuit-QED

    Author : Ingrid Strandberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Continuous variable quantum computing; quantum supremacy; quantum state engineering; negative Wigner function; quantum advantage;

    Abstract : This licentiate thesis is an extended introduction to the appended papers, which pertain to finding quantum states that are useful for continuous variable quantum computing. The useful states are characterized by a negative Wigner function. READ MORE

    Abstract : The concept of a quantum computer was invented in the beginning of the 1980s as a quantum generalization of the reversible classical computer. After discoveries in the middle of the 1990s of quantum algorithms, which wouldsolve some problems considered intractable for classical computers, the field of quantum computing has developed rapidly.

  7. 5. 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.
