Quantum cookies

We celebrate milestones (such as a student passing his or her qual, prelim exam, or thesis defense) with a giant cookie.

Prelim exam: enhancing weak measurements by recycling light.
Thesis defense: based on an example of chromatic dispersion in the student's thesis.
Prelim exam: single photons and human vision. A depiction of the observer's visual field in our experiment.

Prelim exam.
Thesis defense on March 15, 2012.
Two out of three passed the qualifying exam in 2016.

Prelim exam: Superdense Teleportation from the ISS.
Prelim exam: Integrated Photonic Sources Towards Practical Quantum Networking.

Ode to Entangled States

Photons twins, at birth separated
And yet they remain so well correlated
Their colors, directions and spins syncopated
No wonder these states are so celebrated

If that one goes this way, this one goes that
If this one comes early, that one comes late
Like two random roulette wheels, yet somehow both “fixed”
To hit the same number though they’re never mixed

They drove EPR to say “It’s incomplete”
They’ve got the Bell inequities beat
When factoring primes they allow you to cheat
Who knows what new marvel is next at our feet

Just out of reach were problems that dangled
Current attempts to solve them seem wangled
Perhaps what’s required is something new-fangled
Enter the states called hyper-entangled
