Thermal Light N-qubit

Tao Peng (PhD Advisor: Yanhua Shih)
UMBC Physics Department

2:30-3:00 Tuesday, 22 October 2013, ITE 325b

This talk will discuss the equipment and optical elements that required for building the incoherent thermal source, the qubit, and the detection scheme of the intensity fluctuation-fluctuation correlation.

All optical XOR, CNOT gates with initial insight
for quantum computation using linear optics

The design for an all-optical XOR gate is proposed. The basic idea is to split the input beams, and let them cancel or strengthen each other selectively, or flip the encoded information based on their polarization properties. The information is encoded in terms of polarization of the beam. Polarization of a light beam is well understood, hence, the design should be feasible to implement. The truth table of the optical circuit is worked out and compared with the expected truth table. Then it is demonstrated that the design complies with the linear behavior of the XOR function.

Next, based on a similar idea, the design of an all-optical CNOT gate is proposed. The truth table for the gate is verified. Then, it is discussed how this approach can be used for Linear Optics Quantum Computation (LOQC). It is shown that a Hadamard gate, a rotation gate, and a CNOT gate make up a universal set of quantum gates based on linear optics. This novel approach requires no additional power supply, extra input beam or ancilla photon to operate. It also does not require an expensive and complex single photon source and detector. Only narrowband laser sources are required to operate these gates.

Every week we feature a set of comics created exclusively for WDD.

The content revolves around web design, blogging and funny situations that we encounter in our daily lives as designers.

These great cartoons are created by Jerry King, an award-winning cartoonist who’s one of the most published, prolific and versatile cartoonists in the world today.

So for a few moments, take a break from your daily routine, have a laugh and enjoy these funny cartoons.

Feel free to leave your comments and suggestions below as well as any related stories of your own…

The UMBC ACM student chapter will host the second meetup of Baltimore Code Craftsmanship user group at 6:45pm on Thursday, October 24 in the ITE building on the UMBC Campus.

This meetup is for the students and software developers in the Baltimore area that care about the quality of their work and want to practice and improve their programming skills, share what they know and learn new things from others.

Members of the UMBC community can RSVP for the event by completing this form. More details can be found on the form or below. Participants outside of the UMBC community should register on the meetup site. Registration for this meetup is available for a limited number of participants.

This is a hands on coding user group with no presentations. Each meeting will be a dojo where we will go through a challenging software craftsmanship exercise that focuses on clean code, test-driven development, design patterns, and refactoring. We will pair up and practice on a kata in order to learn and apply the values, principles, and disciplines of software craftsmanship. Come with your laptop equipped with your favorite programming and automated unit testing environment. If you don’t have a laptop, come anyway, we will need only one laptop for every two people. Be prepared to pair up, learn, share and have fun!

The event is open to all UMBC students, however programming ability is required. Interested faculty members can join in too! This can also be a good opportunity to network with professionals from various companies and get yourself noticed for any job opportunities that exist.

If you have questions or suggestions, send email to Primal Pappachan (Sorry, you need javascript to view this email address. ) or Vladimir Korolev (Sorry, you need javascript to view this email address. ).

How much would you be willing to pay for Sony’s upcoming gaming console?

Gamers in Brazil are are asking themselves that question quite a bit these days.

In Brazil, the Playstation 4 will cost you an arm and a leg (or two), plus your wallet laden with cash and a debit card (or two). The console will launch at 3,999 Brazilian Real, or approximately $1850 US dollars.

Why so much? According to Sony Brazil, Brazil’s heavy import taxes account for 60 to 70 percent of the cost.

Keep in mind that the average Brazilian earns far lower wages than the average American earns.

While the PS4 seems to have an advantage over the Xbox One heading into the holiday launch season in the US, in Brazil the reverse may be true. The Xbox One may have an edge over the crazy expensive PS4 for retailing at a mere $1015 US dollars.

It will be interesting to see just how many consoles are sold in Brazil in the year ahead.

At those prices, you can be sure  there will soon be a thriving market for smuggled consoles… they might cost you just an arm and one leg.
