CQC2T Seminar (UNSW Sydney) Coupled erbium ions in silicon

Speaker - Dr Chunming Yin: Erbium has been use widely in fibre optics technology for its telecom wavelength optical transition and it has proven to have long spin life-time and coherence time [1]. Optical access…

CQC2T SEMINAR (UNSW Sydney): Single-electron spin qubits in isotopically-enriched silicon at low magnetic field

SPEAKER -  Dr Tuomo Tanttu, UNSW Sydney:   Many single-electron spin qubits employ magnetic fields at the order of 1 Tesla or above to enable quantum state readout via spin-dependent-tunnelling to an electron reservoir. This…

CQC2T Seminar (UNSW Sydney): Repetitive electron spin readout in a silicon quantum dot

Speaker - Dr Jun Yoneda, UNSW Sydney: Although single-shot measurement of a silicon electron spin qubit is now a laboratory routine, the quantum non-demolition (QND) implementation remains a key challenge towards error correction. A QND…

CQC2T Seminar (UNSW Sydney): Nagaoka ferromagnetism in a quantum dot plaquette

Speaker - Dr Juan Pablo Dehollain, UTS: The analytical tractability of Nagaoka ferromagnetism makes it a convenient model to explore the capabilities of quantum simulators of collective electron interactions. However, the small ground-to-excited state energy…

CQC2T Seminar (UNSW Sydney): Charge detection mechanism study of single erbium ion in a silicon transistor by pulsed light

Speaker -  Mr Guongchong Hu, UNSW Sydney: Here we would report the charge detection mechanism of a single erbium ion in a silicon transistor by pulsed light. Erbium atoms were implanted in a silicon transistor…

CQC2T Seminar (UNSW Sydney): A silicon quantum-dot-coupled nuclear spin qubit

Speaker - Dr Wister Huang: Nuclear spins in the solid state have long been envisaged as a platform for quantum computing, due to their long coherence times and excellent controllability. Measurements can be performed via…

CQC2T Seminar (UNSW Sydney): Development of 3D P in Si quantum computing architecture for error correction

Speaker - Mr Mitchell Kiczynski, UNSW Sydney: Phosphorus donor devices in silicon fabricated using STM hydrogen resist lithography are typically fabricated in a 2D design using a single lithographic layer. However in order to achieve…

CQC2T Seminar (UNSW Sydney): Coherent spin control of s-, p-, d- and f-electrons in a silicon quantum dot

Speaker - Ross Leon, UNSW Sydney: Once the periodic properties of atoms were unveiled, chemical bonds could be understood in terms of the valence of atoms. Ideally, this rationale would extend to quantum dots,and quantum…

CQC2T Seminar (UNSW Sydney): Detecting single infrared photons with 95% system efficiency

Speaker - Ian Berkman, UNSW Sydney: The past decade has seen an astonishing increase in interest in single photon detector technologies with high detection efficiency and fast reset times. Besides single-photon detectors being one of…
