For the first time, researchers at the University of Waterloo's Institute for Quantum Computing (IQC) and the University of Innsbruck in Austria have performed a quantum simulation of a two-dimensional particle physics theory on a qudit quantum computer, bringing us closer to understanding nature at its most fundamental level.

According to the Standard Model of Cosmology, the expansion of our universe is driven by the simplest possible version of dark energy: an unchanging 'cosmological constant' called lambda.  "It's the start of a new era," says Will Percival, professor and director of the Waterloo Centre for Astrophysics at the University of Waterloo, and associate faculty at Perimeter Institute for Theoretical Physics.

McGill team discovers a surprising electrical effect that remains stable despite dramatic changes in temperature Electronic devices rely on materials whose electrical properties change with temperature, making them less stable in extreme conditions. A discovery by McGill researchers that challenges conventional wisdom in physics suggests that bismuth, a metal, could serve as the foundation for highly stable electronic components.

McGill astronomers place FRB 20240209A in a region of space associated with a 'dead' galaxy, one that is no longer forming stars Astronomers studying the origins of enigmatic fast radio   bursts (FRBs) have made a groundbreaking discovery that could transform our understanding of the universe's most powerful and mysterious signals.

Two UCalgary researchers part of University of New South Wales team that created a 'Schrödinger's cat' inside a silicon chip A team led by quantum engineers at the University of New South Wales - that includes two UCalgary researchers - has demonstrated a well-known quantum thought experiment in the real world.

McGill-led research team's findings point to neutron stars as the probable source of fast radio bursts, one of the universe's most perplexing phenomena   An international team of scientists led by McGill researchers has provided the clearest evidence yet that some fast radio bursts (FRBs) - enigmatic, millisecond-long flashes of radio waves from space - originate from neutron stars, the ultra-dense remnants of massive stars that have exploded in a supernova.

A high-energy gamma-ray flare from the super-massive black hole in the Messier 87 (M87) galaxy was observed in 2018 for the first time in nearly a decade, thanks to an international effort involving McGill researchers. This discovery has yielded important insights into the physics of black hole jets, which are among the most efficient engines for distributing energy from the inside of a galaxy to the expanse of the Universe.

Quantum information is fragile and often difficult to protect during experiments. Protecting qubits from accidental measurements is essential for controlled quantum operations, especially during state-destroying measurements or resets on adjacent qubits in protocols like quantum error correction. Current methods to preserve atomic qubits against disturbances can waste coherence time, extra qubits, and introduce errors.

UdeM astronomers find a way to measure temperature changes in a star with greater-than-ever precision, a breakthrough that promises to be particularly useful for detecting and studying exoplanets. Étienne Artigau, the UdeM astrophysicist who led the development of an innovative technique that provides precise information on a star's temperature variations.

Waterloo researchers advance nanoscale imaging capabilities. Dynamic nuclear polarization (DNP) has revolutionized the field of nanoscale nuclear magnetic resonance (NMR), making it possible to study a wider range of materials, biomolecules and complex dynamic processes such as how proteins fold and change shape inside a cell.

Physics prof's groundbreaking research shows significant progress in addressing miniaturization issues When we think about charging a battery, we typically imagine that the charge flows one way. For example, when we plug our smartphones in at night, we think of the charge as flowing from the outlet into the phone's battery.

A Canadian team led by René Doyon will help design and build the ANDES spectrograph, which will search for signs of life outside the solar system. In 2014, the European Southern Observatory (ESO) began construction of the world's largest telescope, the Extremely Large Telescope (ELT), in Chile's Atacama Desert, 3,000 metres above sea level.

For the last seven decades, astrophysicists have theorized the existence of "kugelblitze," black holes caused by extremely high concentrations of light. These special black holes, they speculated, might be linked to astronomical phenomena such as dark matter, and have even been suggested as the power source of hypothetical spaceship engines in the far future.

In 2014, the European Southern Observatory (ESO) began construction of the world's largest telescope, the Extremely Large Telescope (ELT), at an altitude of over 3,000 m in Chile's Atacama Desert. Scheduled to enter service in 2028, this giant telescope promises to mark a new era in ground-based astronomy.

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behaviour on a cosmic scale. For the last 100 years, physicists have relied upon Albert Einstein's theory of "general relativity" to explain how gravity works throughout the universe.

Techniques developed by researchers from Western University to create images from old, badly tarnished photographs could also be used to study other historic artifacts and fossils and prevent corrosion on modern materials. Chemistry professor T.K. Sham Chemistry professor Tson-Kong (T.K.

A collaboration of researchers including UBC scientists have observed gravitational waves from the collision of what is most likely a neutron star and an object likely to be a light black hole, 650 million light-years from Earth. The mass of the black hole is 2.5 to 4.5 times the mass of Earth's sun, meaning it falls in the so-called 'mass gap': heavier than heaviest known and theorized neutron stars but lighter than the lightest black holes in our galaxy.

The first cosmological measurements from a global collaboration bring us one step closer to solving the mystery of Dark Energy Canadian scientists working with the Dark Energy Spectroscopic Instrument (DESI) participated in the DESI collaboration's first-year analysis of an exciting new three-dimensional map of the universe, providing details about our cosmological past that have never been seen before.

Materials engineers have spent decades trying to make stronger metals by making their constituent crystals - their grains - smaller. And we mean small: to the nanoscale. That's because the smaller the grain, generally the stronger, tougher and lightweight the metal can be, while less energy is consumed and emitted when it's used in structural applications.

Characteristics of the supermassive black hole at the heart of our galaxy captured in unprecedented detail by international team that includes Waterloo scientists  Long-held theories on how black holes like the one at the centre of our galaxy, the Milky Way, evolve were proven right this week thanks to research made possible by Canadian scientists.
