Clearly these are all deeply philosophical questions about the fundamental nature of reality. Whatever the answer, an interesting future awaits.  Researchers at the University of Vienna study the relevance of quantum reference frames for the symmetries of the world.  Researchers in Singapore have built a refrigerator that's just three atoms big. This quantum fridge won't keep your drinks cold, but it's cool proof of physics operating at the smallest scales.  Researchers have created a new testing ground for quantum systems in which they can literally turn certain particle interactions on and off, potentially paving the way for advances in spintronics.  In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion.  Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons.  They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids.  Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons.  Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks.  Researchers successfully integrated the systems-donor atoms and quantum dots.  A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots.  Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms.
