This is Tzu-Chieh Wei’s homepage located at the YITP, Stony Brook University. I am currently an assistant professor there. 

I received my PhD in physics from the University of Illinois at Urbana-Champaign, working on entanglement theory with Prof. Paul Goldbart and on entangled photons and their applications in quantum information processing with Prof. Paul Kwiat. After obtaining my degree there, I stayed and focused my research on condensed matter, mainly on superconductivity, BEC, and optical lattices. During my career in UIUC, I had cultivated my interests in both condensed matter physics and quantum information science, and had collaborated closely with experimental groups such as Kwiat's Quantum Information Group and Bezryadin's Low Temperature Physics Lab. In addition, I collaborated with Prof. Brian DeMarco and Prof. Smitha Vishveshwara.

In September 2007, I moved from Urbana-Champaign to Waterloo, where I was a postdoctoral fellow associated with Prof. Michele Mosca and Prof. Ashwin Nayak. I was based in IQC and was affiliated with Perimeter Institute for Theoretical Physics through Prof. Mosca and Prof. Nayak. There, I also had the privilege to interact with Prof. Tony Leggett, when he spent two months in Waterloo every summer. In September 2009, I moved from Waterloo to Vancouver, where I worked with Prof. Robert Raussendorf and Prof. Ian Affleck. In September 2011, I moved to Stony Brook and started as an assistant professor at the CN Yang Institute for Theoretical Physics (YITP), Stony Brook University.

Visitor Information:

From JFK: It is highly recommended using JFK airport. Use the Airtrain at JFK to Jamaica Station. (Before exiting Airtrain station at Jamaica, you need to purchase a ticket, which contains 5 dollars for Airtrain and LIRR train fare to Port Jefferson or Stony Brook. (Check the timetable to determine whether it is a peak or off-peak.) At Jamaica Station, take the train (Long Islands Rail Road) towards Port Jefferson and Stony Brook Station (next to the campus) is the last stop before Port Jefferson Station. [Note that you may need to transfer at Hungtington or Hicksville, but it is very easy.] If you stop at Port Jefferson, you need to take a taxi to Danfords.

From LGA, you need to arrange a shuttle, e.g., SuperShuttle or else you can take a taxi to Jamaica Station, then follow the above instruction to Stony Brook or Port Jefferson.

From New Havens, Boston or north east by train: take Amtrack to Bridgeport, CT. Go to the ferry terminal, take the ferry from Bridgeport to Port Jefferson. Usually visitors are accommodated in Danfords Hotel, which is right next to the ferry at Port Jefferson.

From Danfords Hotel to Stony Brook, there is a hotel shuttle. Ask the front desk the night before to arrange. Usually there are visitors to Simons Center using that shuttle service as well. The shuttle driver knows Simons Center. YITP is at the 6th floor of Math Tower, next to Simons Center.
