David P. DiVincenzo (born 1959) is an American theoretical physicist. He is the director of the Institute of Theoretical Nanoelectronics at the Peter Grünberg Institute at the Forschungszentrum Jülich and professor at the Institute for Quantum Information at RWTH Aachen University. With Daniel Loss (at the University of Basel), he proposed the Loss–DiVincenzo quantum computer in 1997,D. Loss and D. P. DiVincenzo, "Quantum computation with quantum dots", Phys. Rev. A 57, p120 (1998); [https://arxiv.org/cond-mat/9701055 on arXiv.org in Jan. 1997] which would use electron spins in quantum dots as qubits.{{cite news |last=Hellemans |first=Alexander |title=David DiVincenzo on his Tenure at IBM and the Future of Quantum Computing |url=https://spectrum.ieee.org/david-divincenzo-on-his-tenure-at-ibm-and-the-future-of-quantum-computing |date=2 October 2015 |work=IEEE Spectrum |access-date=14 December 2015 }}
Career
In 1996, during his research at IBM, he published a paper "Topics in Quantum Computing"{{Cite journal|title = TOPICS IN QUANTUM COMPUTERS|last = DiVincenzo|first = David|date = 16 December 1996|journal = Mesoscopic Electron Transport|arxiv = cond-mat/9612126}} which outlined the five minimal requirements he predicted were necessary for creating a quantum computer. It has since become known as the "DiVincenzo criteria"{{Cite web|title = Proposed modular quantum computer architecture offers scalability to large numbers of qubits|url = http://phys.org/news/2014-02-modular-quantum-architecture-scalability-large.html|website = phys.org|publisher = Phys.org |accessdate = 2015-12-15}}{{Cite journal|title = Efficient quantum computing using coherent photon conversion|journal = Nature|date = 2011-10-20|issn = 0028-0836|pages = 360–363|volume = 478|issue = 7369|doi = 10.1038/nature10463|first1 = N.

The DiVincenzo criteria that a quantum computer implementation must satisfy are as follows:{{Cite journal|title = The Physical Implementation of Quantum Computation|journal = Fortschritte der Physik|issn = 0015-8208|pages = 771–783|volume = 48|issue = 9–11|doi = 10.1002/1521-3978(200009)48:9/11<771::aid-prop771>3.0.co;2-e|first = David P.|last = DiVincenzo|arxiv = quant-ph/0002077|year = 2000|bibcode = 2000ForPh..48..771D| s2cid=15439711 }}
- A scalable physical system with well-characterized qubits,
- The ability to initialize the state of the qubits to a simple fiducial state, such as to ,
- A "universal" set of quantum gates,
- Long relevant decoherence times, much longer than the gate-operation time,
- A qubit-specific measurement capability.
For quantum communication, the act of transmitting intact qubits from place to place, two additional criteria must be satisfied:
6. The ability to interconvert stationary and flying qubits, and
7. The ability to transmit flying qubits between distant locations.
