A new generation of application specific quantum computers has shown great promise in solving exponentially hard problems that are inaccessible to classical computers, by employing innovative designs that do not utilize traditional gate-based architectures. The real world problems that can be treated range from issues important to industry, to the most challenging problems in cosmology. This article will explain these novel approaches being investigated at Swinburne University and elsewhere, with experiments and theory planned or underway in Australia, Japan, Europe and the USA.
In September 2015, gravitational waves (GWs) were detected for the first time by the LIGO detectors, the two laser interferometers in the United States. It was found that detected GWs originate from the coalescence of two black holes (BHs) in a binary, each weighing about 30 times the mass of the Sun (30 solar mass). Although there have been indirect observations of BHs in the X-ray binaries, their masses are at most 15 solar masses.
The UFFO (Ultra-Fast Flash Observatory) Pathfinder for gamma-ray bursts (GRBs), and the TUS (Transient Ultraviolet Setup) telescope for ultrahigh energy cosmic rays, were launched onboard the Lomonosov satellite at 11:00 a.m., April 28, 2016, by the Soyuz-2.1a rocket, which first launched from the Vostochny Cosmodrome.
The early contributions of ancient China to optics predate those of Euclid, but are little known in the west. During the Warring States period, 2400 years ago in China, Mo Zi, a philosopher, thinker and scientist, stated explicitly the concepts of linear optics: the straight line propagation of light, reflection of light by planar, concave and convex mirrors, and the pinhole camera. Refraction of light was also discovered then, and the refractive index of water was measured to be 1.25, which is very close to the modern value of 1.33. These are recorded in the Book of Mo Zi. In the early Western Han Dynasty, Liu An, King of Huai-Nan, also compiled several works, where novel optical devices are …
IInGaAs/GaAsSb superlattice structure is very attractive in photodetectors and light emitting devices. However, the growth of high quality GaAsSb alloys is a challenge. Recently, a research team from the Chinese Academy of Sciences (CAS) has successfully obtained high quality InGaAs/GaAsSb superlattice structures based on a broad analysis of growth mechanisms .
