Stealth aircraft in the Canadian arctic will be no match for a new quantum radar system.
Researchers at the University of Waterloo are developing a new technology that promises to help radar operators cut through heavy background noise and isolate objects —including stealth aircraft and missiles— with unparalleled accuracy.
Port-based teleportation (PBT) is a variant of the well-known task of quantum teleportation in which Alice and Bob share multiple entangled states called "ports". While in the standard teleportation protocol using a single entangled state the receiver Bob has to apply a non-trivial correction unitary, in PBT he merely has to pick up the right quantum system at a port specified by the classical message he received from Alice.

The invention of quantum physics in the early 20th century forced scientists to reconsider many cherished ideas from classical physics, leading to revolutionary changes in our scientific and philosophical understanding of the universe. Quantum phenomena have also proven to be a rich source of metaphors and inspiration for fiction.
Cavity optomechanics, a field which studies the interplay between the photonic and phononic modes of an optical cavity, has seen rapid progress over the past decade. Micro/nano-scale optomechanical cavities have demonstrated potential for use in technologies such as quantum-limited metrology and transduction, as well as probes for exploring the fundamental nature of quantum mechanics.
With traditional classical complementary metal oxide semiconductor (CMOS) computing struggling to keep up with Moore’s law, interest in quantum computing has exploded and the University of Waterloo is at the centre of this technological revolution.
The concept for his latest startup is something straight out of a superhero movie. Just like Batman used high-frequency sonar signals from millions of cell phones to visualize the location of villains throughout Gotham City in Dark Knight, entrepreneur Taj Manku is developing new software that could soon allow our cell phones to see in the dark.
The runtime of Adiabatic optimization algorithms are typically characterized by the size of the spectral gap of the corresponding Hamiltonian. Gap analysis nonetheless remains a challenging problem with few general approaches.

We use the polynomial method to prove optimal or nearly optimal lower bounds on the quantum query complexity of several problems, resolving open questions from prior work. The problems studied include k-distinctness, image size testing, k-junta testing, approximating statistical distance, approximating Shannon entropy, and surjectivity.
