How Much Does a Quantum Computer Cost? (2024)

Here’s the deal: classical computers rely on bits to measure processing capability and power but the arrival of quantum computers has completely obliterated traditional PC performance. So much so that security experts are worried that in the wrong hands, they could mean the end of encrypted communications and internet as we know it. Surely these things can’t be cheap?

Power doesn’t come cheap. And for now, quantum computers are out of the reach of the mass market.

Quantum vs Classical computing

Before we get to how much these things cost, let’s talk about the power difference between the two.

That laptop or PC you’re using has either a 32-bit or 64-bit processor. It can handle data in the form of 1s and 0s only.

A 32-bit CPU can handle 34,359,738,368 bits at once. A 64-bit processor holds double the number of bits than that.

With us so far? Good. Because here is where it gets more complex.

Quantum computers rely on qubits. A qubit can be both or either 1 and 0 at any time. In simpler terms, It exists in both states or even one of them – a total of four states. This basically translates to an exponential increase in power than traditional bits.

Fact: A 100 Qubit quantum computer is more powerful than all the supercomputers on Earth combined.

How much do quantum computers cost?

Now for the burning question – how much do these darn things cost?

• Commercial quantum computers like D-Wave One with 50 qubits – $10,000,000.
• D-Wave’s 2000 qubit quantum computer – $15 million.
• For every extra qubit in processing power – $10,000.
• SpinQ’s portable quantum computer with 2 qubits – $5,000.

It is interesting how these computers do their quantum processing calculations. SpinQ’s ‘cheap’ model, which is aimed at schools, relies on magnetic resonance for limited problem-solving capabilities. In comparison, D-Wave’s 2000Q model employs a topographical map to solve problems.

Given these examples, researchers agree that the ‘true state quantum computer’ is yet to happen. These computers need to achieve zero errors and maximum stability, a far cry from existing quantum computers. Nevertheless, this is a only matter of when. These new machines will end up costing billions, and will become a reality after a decade.

Currently, IBM has the fastest quantum computer with 127 qubit processing capability.

Who wants to pay for quantum computing?

Over the years, there has been billions poured into the research and development of quantum computers by private and public entities.

These industries stand to benefit the most with problem-specific quantum computing capabilities:

• Pharma
• Chemical
• Manufacturing
• Defense
• Logistics

The problems they have can’t be solved by applications in use today. But the processing power and complex problem-solving capabilities possessed by quantum computers can.

How much energy do you need to run a quantum computer?

Turns out that quantum computers are resource-hungry. They need proper cooling on top of the energy to run efficiently.

It is estimated that a quantum computer that consumes 25 kilowatt per year will require $25,000 per unit to run in the US! Its hard not to see corporations paying millions of dollars into just keeping their quantum rigs cool and running.

The D-Wave model relies on -460 degrees Fahrenheit to keep running in a stable form.

Types of Quantum Computers

In 2023, various types of quantum computers will be in development and production, categorized based on the qubit technology they employ. Presently, there are five prominent qubit methodologies:

1. SUPERCONDUCTING

The most prevalent quantum computers use superconducting qubits. These devices employ tiny electrical circuits and manipulate qubits, often crafted from superconducting materials.

Leading companies in this field include Google, Microsoft, Rigetti Computing, Quantum Circuits, Inc., IBM, and IQM.

2. TRAPPED IONS

Another popular approach utilizes ion-trap quantum computers. These systems employ ions, atoms or molecules with a net electric charge, confined and managed using electric and magnetic fields to store and process quantum information.

Companies advancing in this area include Quantinuum, ionQ, Alpine Quantum Technologies, and eleQtron.

3. PHOTONIC

Photonic quantum computers, another significant approach, harness photons (particles of light) for carrying and processing quantum information.

Commercial entities embracing this qubit technology include PsiQuantum, Xanadu, and ORCA Computing.

4. NEUTRAL ATOMS

Quantum computing with neutral atoms involves utilizing neutral atoms suspended in a high vacuum through arrays of precisely focused laser beams known as optical tweezers. These arrays have been scaled to accommodate over 100 alkali atoms.

Commercial players in this include ColdQuanta, QuEra, and Pasqal.

5. QUANTUM DOTS

Quantum dot quantum computing employs qubits composed of pairs of quantum dots, specifically silicon qubits, making them valuable for various applications, including quantum computing.

Companies invested in this approach include Diraq, Intel, and Quantum Motion.

6. OTHER QUBIT MODALITIES

Additional approaches include utilizing electrons on helium, quantum computers integrating silicon CMOS, and nitrogen-vacancy centers (N-V centers).

It’s important to note that each type of quantum computer has its own distinct strengths and weaknesses, and their suitability varies depending on the specific problems they are designed to address.

Are Quantum Computers and Supercomputers the same?

Quantum computers and supercomputers represent two advanced computing systems. They have distinct characteristics:

Can Quantum computers be monitored for standards?

The International Organization for Standardization (ISO) has introduced its first-ever set of standards for Quantum Key Distribution (QKD) security requirements. These standards provide a comprehensive framework to assess the security of QKD systems, covering various aspects of QKD modules and protocols.

The standards, recognized as a significant advancement in quantum encryption, will usher in a new era of secure data transmission. ISO’s document establishes fundamental security requirements for QKD modules, addressing security challenges and categorizing QKD protocols.

The security requirements for conventional network components in QKD modules are integrated into the wider ISO/IEC 15408 framework. ISO, a global organization with 169 member countries, focuses on creating international standards to tackle global challenges and promote innovation.

These QKD security standards demonstrate ISO’s dedication to enhancing cybersecurity. They will play a crucial role in ensuring the security of quantum communication systems, contributing to a more secure and resilient digital future.
