Journal ArticleDOI
Precision tomography of a three-qubit donor quantum processor in silicon
Mateusz T. Mądzik,Serwan Asaad,Akram Youssry,Benjamin Joecker,Kenneth Rudinger,Erik Nielsen,Kevin Young,Timothy Proctor,Andrew Baczewski,Arne Laucht,Vivien Schmitt,Fay E. Hudson,Kohei M. Itoh,Alexander M. Jakob,Brett C. Johnson,David N. Jamieson,Andrew S. Dzurak,Christopher Ferrie,Robin Blume-Kohout,Andrea Morello +19 more
TL;DR: In this article , the authors demonstrate universal quantum logic operations using a pair of ion-implanted 31P donor nuclei in a silicon nanoelectronic device, and demonstrate entanglement between the two nuclei and the shared electron by producing a Greenberger-Horne-Zeilinger three-qubit state with 92.5(1.0)% fidelity.
Journal ArticleDOI
Conditional quantum operation of two exchange-coupled single-donor spin qubits in a MOS-compatible silicon device
Mateusz Madzik,Arne Laucht,Fay E. Hudson,Alexander M. Jakob,Brett C. Johnson,David N. Jamieson,Kohei M. Itoh,Andrew S. Dzurak,Andrea Morello +8 more
TL;DR: In this article, the authors demonstrate the conditional coherent control of an electron spin qubit in an exchange-coupled pair of 31P donors implanted in silicon, where the coupling strength is measured spectroscopically with high precision.

Conditional quantum operation of two exchange-coupled single-donor spin qubits in a MOS-compatible silicon device
Mateusz T. Mądzik,Arne Laucht,Fay E. Hudson,Alexander M. Jakob,Brett C. Johnson,David N. Jamieson,Kohei M. Itoh,Andrew S. Dzurak,Andrea Morello +8 more
TL;DR: In this paper, the authors demonstrate the conditional, coherent control of an electron spin qubit in an exchange-coupled pair of donors implanted in silicon, and the coupling strength, $J = 32.06 \pm 0.06$ MHz, is measured spectroscopically with unprecedented precision.
Journal ArticleDOI
Nanoscale mechanical surface properties of single crystalline martensitic Ni–Mn–Ga ferromagnetic shape memory alloys
Alexander M. Jakob,Alexander M. Jakob,M Müller,M Müller,Bernd Rauschenbach,Bernd Rauschenbach,Stefan G. Mayr,Stefan G. Mayr +7 more
TL;DR: In this paper, contact resonance atomic force microscopy (CR-AFM) is employed for nano-mechanical surface characterization of single crystalline 14M modulated martensitic Ni-Mn-Ga (NMG) thin films grown by magnetron sputter deposition on (001) MgO substrates.
Journal ArticleDOI
