Computing is an expansive field that encompasses the study and utilization of computer systems and information processing. This can involve anything from hardware design and software development to data analytics and algorithm creation.
1. **Quantum Computing**: Quantum computing is a rapidly emerging technology that leverages principles of quantum mechanics to process information. Quantum computers use quantum bits, or qubits, which can represent multiple states at once, bringing about the potential for exponential computational power. However, significant challenges in achieving scalability and stability remain, but progress is consistently being made. For instance, Google recently debuted its new Quantum AI campus, where it plans to build a useful, error-corrected quantum computer by 2029.

2. **Edge Computing**: The traditional model of cloud computing, where data is sent back and forth between devices and remote data centers, has been challenged by the rise of edge computing. Edge computing involves processing data closer to the location where it is needed or generated, reducing latency and potentially increasing security. It’s a key technology behind the Internet of Things (IoT) and is showing great potential in industries like manufacturing and telemedicine. (Source: https://www.nature.com/articles/s41586-020-2987-5)
3. **Decentralized Computing**: Blockchain and Distributed Ledger Technology (DLT) represent an evolution in computing paradigm towards decentralization. Blockchain’s data decentralization has seen a wide range of applications, from cryptocurrency to supply chain tracking, and has major implications for data security and transparency. Ethereum’s recent move to a more energy-efficient system (Ethereum 2.0) demonstrates the ongoing progress in this space.

4. **High-Performance Computing (HPC)**: HPC involves the use of supercomputers and parallel processing techniques when handling complex data computations. It’s particularly critical in fields like scientific research, climate modeling, data analytics, and more. Multiple nations are investing heavily in HPC, China currently operates the most powerful supercomputer (Source: https://www.top500.org/lists/top500/2021/06/) while the US has announced plans to build the first exascale computer by 2021(Source: https://www.energy.gov/articles/doe-amd-unveil-exascale-computer-project).
5. **Neuromorphic Computing**: Neuromorphic computing involves the design of systems that mimic the neurological structure and operation of the human brain. The goal is to develop machines that can process and interpret data as effectively and efficiently as human brains do. This technology can greatly improve the performance and efficiency of machine learning and AI applications. Intel’s neuromorphic research chip, Loihi, is indicative of progress in this area.
