Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the '0' and the '1'. However, spins in real devices also interact with light and vibrations known as bosons, greatly complicating calculations. Researchers now demonstrate a way to describe spin-boson systems and use this to efficiently configure quantum devices in a desired state.

Researchers have investigated how spiders listen to their environments through webs and found that the webs match the acoustic particle velocity for a wide range of sound frequencies. Playing sound ranging from 1 Hz to 50 kHz for the spiders and measuring the spider silk motion with a laser vibrometer, they found the sound-induced velocity of the silk was the same as the particles in the air surrounding it. This confirmed the mechanism that these spiders use to detect their prey.

Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems. However, these methods reach their limits when so-called sign oscillations occur. This problem has now been solved using the new method of wavefunction matching.

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's possible. That's exactly what physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world's longest fiber distance between two quantum memory nodes to date.

Using interference between two lasers, a research group has created an 'optical conveyor belt' that can move polaritons -- a type of light-matter hybrid particle -- in semiconductor-based microcavities. This work could lead to the development of new devices with applications in areas such as quantum metrology and quantum information.

As often as four days a week, Boeing EA-18G Growler electronic attack aircraft based at Naval Air Station Whidbey Island fly loops overhead as pilots practice touch-and-go landings. The noise is immense. New research shows that the noise isn't just disruptive -- it presents a substantial risk to public health.
