  "abstract": "In [R. Jozsa, B. Kraus, A. Miyake, J. Watrous, Proc. R. Soc. A {\\bf 466}, 809-830 (2010)] it has been shown that a match gate circuit running on n qubits can be compressed to a universal quantum computation on \\log(n)+3 qubits. Here, we show how this compression can be employed to simulate the Ising interaction of a 1D--chain consisting out of n qubits using a universal quantum computer running on log(n) qubits. We demonstrate how the adiabatic evolution can be realized on this exponentially smaller system and how the magnetization, which shows a quantum phase transition, can be measured.",
