The development of quantum computers may create serious cyber-security threats. The NSA has recently released statements expressing their concern over the potential of quantum computing to foil the cryptography protecting all data to date. Furthermore, the use of quantum computers may become widespread before many people expect.
A powerful quantum computer could crack the cryptographic algorithms that keep our data safe. While managed detection and response services are highly effective at keeping today's data safe, these services wouldn't be able to protect data from a quantum computer. Quantum computers could even break the algorithms that are used by New York's stock exchange. This could lead to the collapse of the stock market.
How Do Quantum Computers Work?
Quantum computers use quarks as bits (qubits) rather than bits made of silicon. The device's bits are the smallest particles in the universe, and this will make it possible for quantum computers to have a larger number of bits than conventional devices.
Quantum computers could have drives that contain hundreds of millions of terabytes or more. It's even possible that mobile devices could be this powerful!
Also, quantum computers use a code that is different than binary code. In fact, quarks can exist in a state referred to as a superposition. This means that the qubits can exist in more than one position at the same time! Therefore, a qubit can be both 0 and 1 at the same time.
As a result, the amount of numbers that can be stored on the device doubles each time a qubit is added. Ten qubits can store 1,024 numbers, and 11 qubits can store 2048 numbers. If you have a quantum computer that has 100 qubits, it can store more than 1 nonillion numbers! This is the equivalent of 10 to the 30th power! If the device has 500 qubits, the quantum computer is capable of storing more numbers than there are atoms in the universe.

Quantum Computers Are Impossible To Hack
It would be very difficult to track down a cyber-attack that used quantum computers. This is because quantum computers cannot be hacked by classical computers. In addition, they cannot be hacked by other quantum computers.
Are There Quantum Computers That Are Currently On The Market?
There currently is a quantum computer on the market that has 128 qubits. While the device's price is out of the range of most individuals and businesses, it's well within the budget of large corporations and governments. It's capable of performing the following functions that are difficult for conventional computers:
Solving optimization problems
Developing machine learning algorithms
What Research Is Being Done To Develop More Advanced Quantum Computers?
There are a number of companies that are working on creating better quantum computers. These efforts have quite a substantial budget. Therefore, it's likely that major advancements in the field will occur in the near future.
Changes To Cryptography Will Be Necessary
The creation of cryptography that would protect classical computers from quantum computers is still in its early stages. Quantum computers are likely to become available several years before effective cryptography has been developed to keep classical computers safe.
The Race To Develop The First Quantum Computer
It's likely that one of the world's governments will be the first to develop a quantum computer that can break through modern-day encryption. The government that develops this technology first is likely to gain a large amount of political leverage over other nations. Furthermore, it's far too soon to speculate about which country will be the first to develop a quantum device that can break through modern-day encryption.
