This exhaustive quality-research paper covers the field of emerging materials and their intrinsic properties and including how they can be used in the future in quantum technologies. The arrival of quantum mechanics is one of the most important scientific discoveries of the 20th century, with the promise of new computer generations, enhanced information transfer and precision measurement. However, the development of future quantum technology is highly dependent on the discovery of new materials that enable us to control quantum phenomena. This article carefully considers a range of advanced materials that have emerged recently, such as novel superconductors, topological insulators and graphene derivatives, to explore the unique quantum properties of these materials and how they can be exploited in quantum devices. By using advanced experimental techniques, including angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy (STM), advanced instruments that allow us to probe electronic structures, spin textures and topological properties with atomic electron and spin resolution, the areas with most interesting quantum properties can be discovered, key for the development of quantum technologies.

Quantum coherence is one of the most important properties for using the quantum features of materials for information processing. Through quantum states and entanglement, the quantum coherence can be manipulated and enhanced, which is also intertwined with the environment. Better understanding of quantum coherence and the mechanisms of decoherence can help to improve future generations of quantum technologies. The results reported here help to explain the mechanisms leading to design and performance of new materials for the quantum technology revolution. Studying advanced materials not only advance the understanding of quantum nature but will also power future quantum computing, quantum communication and quantum sensing devices.

The recently emerged field of quantum technology is aiming to employ quantum coherence and entanglement for realization of next generation sensors, standards, imaging systems, secure communication and computers.Although applications of quantum technologies cover a broad spectrum and their development stage varies from early demonstrations to commercially available devices, many challenges have been identified.The first includes tailoring materials for quantum technologies, which is playing an essential role in technological applications of quantum science.Solid state systems allowing long coherence time are essential for quantum computation and quantum sensing.Ultrapure materials with tailored isotopic content are important for reaching long coherence time of spin qubits (Awschalom et al., 2013).The ability to place single dopants with high precision and form spin qubits at desired location is essential for both quantum computing and quantum sensing applications (McCallum et al., 2012;Smith et al., 2019).The performance of different types of qubits is usually benchmarked in terms of controllability and coherence time.Usually solid-state systems allow fast control, but exhibit fast decoherence owing to complex environment.It is therefore important to search for new types of qubits combining isolation from environment and access via fast coherent control and readout.Novel approaches combining different quantum systems into build hybrid quantum devices for optimal performance is a promising avenue.Examples of such hybrid approaches are spin systems coupled to superconducting qubits (Kubo et al., 2011) and hybrid nuclear-electronic qubits (Morley et al., 2013).Optimal protocols for quantum technologies requires extension of coherence time of qubits beyond the coherence time of the isolated quantum system.The efficient protection toolkit includes dynamical decoupling (Yang et al., 2011) and quantum error correction (Terhal, 2015) based techniques.Although general principles of qubits protection were developed and tested experimentally in different model environments, it is essential to adapt them to realistic environmental noise.In the field of quantum sensing, it is also essential to combine protections against noise with non-reduced sensing performance.Experimental imperfections can be addressed using optimal control tools (Glaser et al., 2015).The development of efficient quantum algorithms is another growing field belonging to quantum software area.On one hand, it is essential to find problems where a quantum computer can outperform classical computers.On the other hand, it is essential to develop an application scenario for a limited number of qubits (Montanaro, 2016).In addition, in order to develop new algorithms, future work must include discoveries of application scenarios of already known algorithms.Application of quantum Fourier transform for sensing is a promising example of such new applications (Vorobyov et al., 2021).Signal processing is another field of quantum software that is becoming essential in applications.Advanced signal analysis protocols, like quantum compressed sensing, can be employed to quantify entanglement in large quantum devices via efficient quantum tomography (Riofrío et al., 2017).

Discoveries in quantum materials, which are characterized by the strongly quantum-mechanical nature of electrons and atoms, have revealed exotic properties that arise from correlations. It is the promise of quantum materials for quantum information science superimposed with the potential of new computational quantum algorithms to discover new quantum materials that inspires this Review. We anticipate that quantum materials to be discovered and developed in the next years will transform the areas of quantum information processing including communication, storage, and computing. Simultaneously, efforts toward developing new quantum algorithmic approaches for quantum simulation and advanced calculation methods for many-body quantum systems enable major advances toward functional quantum materials and their deployment. The advent of quantum computing brings new possibilities for eliminating the exponential complexity that has stymied simulation of correlated quantum systems on high-performance classical computers. Here, we review new algorithms and computational approaches to predict and understand the behavior of correlated quantum matter. The strongly interdisciplinary nature of the topics covered necessitates a common language to integrate ideas from these fields. We aim to provide this common language while weaving together fields across electronic structure theory, quantum electrodynamics, algorithm design, and open quantum systems. Our Review is timely in presenting the state-of-the-art in the field toward algorithms with nonexponential complexity for correlated quantum matter with applications in grand-challenge problems. Looking to the future, at the intersection of quantum information science and algorithms for correlated quantum matter, we envision seminal advances in predicting many-body quantum states and describing excitonic quantum matter and large-scale entangled states, a better understanding of high-temperature superconductivity, and quantifying open quantum system dynamics.
Quantum mechanics has emerged as one of the most transformative scientific revolutions of the 20th and 21st centuries, extending far beyond its initial theoretical foundations into practical applications across engineering, materials science, information technology, and nanotechnology. Its principles, such as wave�particle duality, superposition, and entanglement, form the backbone of modern innovations like quantum computing, quantum cryptography, semiconductor devices, and energy-efficient nanomaterials. This paper investigates the role of quantum mechanics in advancing technological frontiers, with an emphasis on engineering domains such as electronics, computing, and material design. A detailed discussion on quantum principles, their mathematical representation, and their translation into applied engineering technologies is presented. By linking theoretical constructs to real-world devices and emerging applications, this work highlights the significance of quantum mechanics as not only a fundamental science but also as a driver of future innovation.
Quantum phenomena are typically observable at length and time scales smaller than those of our everyday experience, often involving individual particles or excitations. The past few decades have seen a revolution in the ability to structure matter at the nanoscale, and experiments at the single particle level have become commonplace. This has opened wide new avenues for exploring and harnessing quantum mechanical effects in condensed matter. These quantum phenomena, in turn, have the potential to revolutionize the way we communicate, compute and probe the nanoscale world. Here, we review developments in key areas of quantum research in light of the nanotechnologies that enable them, with a view to what the future holds. Materials and devices with nanoscale features are used for quantum metrology and sensing, as building blocks for quantum computing, and as sources and detectors for quantum communication. They enable explorations of quantum behaviour and unconventional states in nano- and opto-mechanical systems, low-dimensional systems, molecular devices, nano-plasmonics, quantum electrodynamics, scanning tunnelling microscopy, and more. This rapidly expanding intersection of nanotechnology and quantum science/technology is mutually beneficial to both fields, laying claim to some of the most exciting scientific leaps of the last decade, with more on the horizon.
