Quantum Science

Three cross-disciplinary branches of quantum science, namely that of: Quantum Chaos, Quantum Biology and Quantum Computation, are concisely addressed herein. The implications of these fields in the progression of science are emphasized. This critique is to be treated as a metacognition on currently contentious branches of science interwoven with the foundations of modern science: Quantum Mechanics, made accessible in layman terms to all systems thinkers.

Dispositional Properties

A central metaphysical thesis of modern science has been the idea that the structure of a physical system can be explained in terms of the properties of its constitutive subsystems. I call this presupposition the Newtonian merological presupposition. After some brief introductory remarks on the role of this presupposition in the methodology of modern physics, and after mentioning some recent challenges to it, I focus my attention on quantum systems. Quantum mechanics is the only highly confirmed theory in which the Newtonian merological presupposition is denied. I argue that the presence of a non-Newtonian (holistic) merological structure is the result of the existence of two different types of properties, and in particular of the existence of genuinely dispositional properties. Genuinely dispositional properties are properties of a system which are not reducible to occurrent properties of the subsystems. This distinction between two different types of properties can be made precise in a lattice theoretical modeling of the possible properties and states attributable to a quantum system. I conclude by giving an example of the sort of genuinely dispositional properties that are constitutive of quantum systems.

The important requirements are stated for the success of quantum computation. These requirements involve coherent preserving Hamiltonians as well as exact integrability of the corresponding Feynman path integrals. Also we explain the role of metric entropy in dynamical evolutionary system and outline some of the open problems in the design of quantum computational systems. Finally, we observe that unless we understand quantum nondemolition measurements, quantum integrability, quantum chaos and the direction of time arrow, the quantum control and computational paradigms will remain elusive and the design of systems based on quantum dynamical evolution may not be feasible.

It is shown that for quantum systems the vector field associated with the equations of motion may admit alternative Hamiltonian descriptions, both in the Schrödinger and Heisenberg picture. We illustrate these ambiguities in terms of simple examples.

Number Of Particles

Interacting quantum systems in the chaotic domain are at the core of various ongoing studies of many-body physics, ranging from the scrambling of quantum information to the onset of thermalization. We propose a minimum model for chaos that can be experimentally realized with cold atoms trapped in one-dimensional multi-well potentials. We explore the emergence of chaos as the number of particles is increased, starting with as few as two, and as the number of wells is increased, ranging from a double well to a multi-well Kronig-Penney-like system. In this way, we illuminate the narrow boundary between integrability and chaos in a highly tunable few-body system. We show that the competition between the particle interactions and the periodic structure of the confining potential reveals subtle indications of quantum chaos for 3 particles, while for 4 particles stronger signatures are seen. The analysis is performed for bosonic particles and could also be extended to distinguishable fermions.

Optically accessible spins associated with defects in diamond provide a versatile platform for quantum science and technology. These spins combine multiple key characteristics, including long quantum coherence times, operation up to room temperature, and the capability to create long-range entanglement links through photons. These unique properties have propelled spins in diamond to the forefront of quantum sensing, quantum computation and simulation, and quantum networks.

Game Changer

There is no doubt that quantum mechanics has become one of the building blocks of our physical world today. It is one of the most rapidly growing fields of science that can potentially change every aspect of our life. Quantum biology is one of the most essential parts of this era which can be considered as a game-changer in medicine especially in the field of cancer. Despite quantum biology having gained more attention during the last decades, there are still so many unanswered questions concerning cancer biology and so many unpaved roads in this regard. This review paper is an effort to answer the question of how biological phenomena such as cancer can be described through the quantum mechanical framework. In other words, is there a correlation between cancer biology and quantum mechanics, and how? This literature review paper reports on the recently published researches based on the principles of quantum physics with focus on cancer biology and metabolism.
