Quantum computing has been the focus of much research, and several systems are being investigated as potential platforms for scalable and fault-tolerant quantum information processing. One interesting approach is the use of trapped ions, which have shown outstanding control and coherence, as well as the ability to grow into more extensive systems. Nevertheless, achieving low temperatures has been a significant hurdle in the advancement of practical quantum computing. The demand for cooling systems adds layers of intricacy and expense, limiting the reach and expansion potential of these technologies. In response, scientists have explored approaches, like leveraging liquid crystals capable of executing quantum functions at ambient room temperatures . Liquid crystals are a unique class of materials with characteristics that fall somewhere between solids and liquids . Their unique qualities, such as their capacity to maintain long-range order and coherence at ambient temperature, make them an appealing choice for quantum computing. Recent research has shown that liquid crystals can store and control quantum information, bringing up new possibilities for the creation of practical quantum computers . Using crystals for quantum computing offers a benefit in attaining high performance at room temperature. In contrast to trapped ion setups that need cooling, quantum computers based on crystals can operate at regular room temperatures, reducing system complexity and cost . This review also delves into liquid crystals that can act as robust single-photon sources. Specifically, cholesteric liquid crystals doped with dye molecules like terylene have shown promise for room-temperature quantum processes. These systems take advantage of the photonic band-gap features of cholesteric liquid crystals, which can improve the emission properties of the dye molecules, resulting in more efficient single-photon generation . These sources that emit photons are currently being worked on to make them efficient, lasting, and pure in polarization. The improvements focus on selecting dye molecules and liquid crystal materials as well as refining photonic band gap structures to match the fluorescence bands of the dyes . For instance, positioning dye molecules to boost excitation efficiency and adjusting the band gap microcavities have been identified as methods for enhancing performance. Moreover, attention has shifted to quantum crystals, which represent a state of matter where electrons act like molecules in liquid crystals-they flow freely but maintain a preferred direction. This property is beneficial for quantum computing as it helps maintain quantum coherence and enables the flow of quantum information at room temperature. The discovery of quantum crystals holds promise for ultrafast quantum computers . Liquid crystals can also be utilized in cavity systems that operate within the realm of quantum mechanics at room temperature. These systems manipulate quantum states by interacting oscillators with cavities. Combining quality oscillators made from materials like silicon nitride with liquid crystals can achieve low thermal noise and high thermal conductanceboth crucial for controlling quantum effects and minimizing photothermal impacts .
