Imagine conducting an MRI, on a single cell instead of the whole  body - taking a picture of the molecule or just a group of molecules  within the cell, identifying and examining the problem areas within DNA,  and coming up with a more precise diagnosis and patient therapy. This  is possible today through the precision of Quantum Computing and  Nanotechnology built into an MRI equipment.
In a recent news  release IBM declared that they are very close to make a breakthrough in  the realms of Quantum computing. As a result of some experimental  successes they are closer to build the first Quantum Computer, that can  take advantage of the oddities of quantum physics and could solve  certain problems in seconds, that would otherwise take present-day  computers billions of years to solve.
Quantum computing is a  computing system based on qubits as opposed to bits; where qubits  (Quantum Bits) are basic units of information in a quantum computer.  While a bit can represent just one of two possibilities such as 0 or 1,  or yes or not, Qubits can represent many more options: 0 or 1, 1 and 0,  the occurrence of multiple combinations of Qubits, and that too  simultaneously. So, Qubit represents an array of possibilities and all  can be calculated simultaneously taking probabilities in account.
The  Qubit concept deals with very small particles (subatomic particles). It  has been proven that a subatomic particle can have different states  simultaneously because the particles are never static. This is evident  because they move very fast, close to the speed of light. So, a particle  state of the particle (Qubit) looks different to different observers  and the particle has several states simultaneously. That is why one  subatomic particle can have different states and probabilities, at the  same time. We can use it to replace bits and get better performance:  Much better performance! And then, when you combine Qubits, that  combination holds an exponentially larger amount of information than  bits. Subatomic logic is much more powerful than binary logic used in  normal computing.
As a result, you can process complicated  information faster. Its main applications are encryption, decryption,  modeling, databases, voice recognition, structure recognition,  simulation and artificial intelligence, plus many others yet  non-existent applications.
Imagine its utilization and effect in  the realm of Healthcare, specifically e-Health. Volumes of  electronically available Patient data, structured, modeled, simulated,  and processed in fractions of seconds - artificial intelligence for  diagnosis and condition predictability with almost 100% accuracy, will  multiply millions of fold, surpassing unthought-of limits.
Quantum  Computing has also proved that two entangled particles share its  existence. That is when one modifies its state, the other also modifies  its own state simultaneously, no matter how far they are in the  universe. That means we can "transport" information from one place to  another without physical movement, just by modifying one entangled  particle state.
In e-Health, this could mean automatic remote and  reliable diagnosis, with electronic patient information, through  immediate communication with entangled subatomic particles. And, with  nano-scale precision applications, this is just the tip of the iceberg.
