This paper will cover the impact of quantum computing and how it will affect the entire landscape, from security to ecommerce and even technologies such as the blockchain. First, it introduces the basics of encryption and compares it to classical computing and how it will differ from the quantum era of computing. The older style of encryption, when used in classical computing, will be defenseless in the age of quantum computing. We go over different types of protections and other theories to protect such attacks if and when they occur from a quantum computer. Our research paper also covers decryption comparing how classical computing decryption can be done manually or even automatically. Still, with the introduction of quantum computing, it would have to utilize quantum mechanical principles to perform cryptography. In addition this paper will also go over how big companies such as IBM and their technology strive to be ahead of their competitors in regards to advancement in the quantum space. One of the biggest companies, such as IBM, is investing in the quantum computing field with a power of 64 Qubits, and it is still in progress of advancement in Qubits. Quantum computing will also bring many benefits, such as fixing old security protocols and encryption issues. It will also solve problems such as key encryption or even make older encryptions stronger when running on a quantum system. In addition, cyber security with quantum computing will come with some negatives which will weaken all classical types of security, such as RSA, DSA, and ECDSA. It can keep trying to compute until it cracks through these classical security protocols. Ecommerce in the future will be handled through quantum computing and more advanced security protocols. Blockchain technology emerged with Bitcoin and is used for secure ways to do transactions and communication between two users. The technology relies more on classical cryptography protocols, and emerging quantum computing will create security issues including areas of blockchain data transparency. As the conclusion on quantum computing which requires future work to be done for implementation of effective strategies to push the classical computing technologies to the quantum era.
